7 tructure and Features FYH all earing Units are manufactured to exacting standards comprising of grease sealed deep groove ball bearings and housings in various forms. elf-aligning units allow for easy installation and are supplied with grease fittings in order to facilitate quick and convenient re-lubrication.. tructure FYH all earing Units are constructed of high carbon chromium bearing steel and have precision honed raceways and riveted steel cages (Fig..). Grease fitting Grease hole linger Outer ring with spherical outside surface Double lip Floack seal all and cage ullet Point set screw Wide inner ring Extra olid base cast iron housing Fig.. tructure of ball bearing units (representative example). Features FYH all earing Units have many features and are available in various models. wide selection of mounted units is offered to fit virtually any application. upreme load capacity and accuracy FYH all earing Units feature an internal structure identical to single row deep groove ball bearings and can bear significant radial load, as well as a great deal of axial load in both directions. The hardened steel balls exhibit a high degree of roundness and the races are highly polished to accoodate a smooth ride at a wide range of speeds. This design allows the bearing unit to self-adjust for shaft deviation and reduce abnormal bearing load. Therefore, the original rated life of the bearing can be guaranteed. ince the spherical outside surface of the bearing is precision ground and the spherical bore of the housing is machined by a boring machine with great accuracy, optimal fitting of the bearing and the housing can be obtained, as well as superior aligning performance. The allowable aligning angle of standard ball bearing units is º, while units with covers is º. Rational self-aligning mechanism and optimal fit FYH all earing Units have the special ability to self-align inside the housing because of the spherical shape of the outer diameter of the bearing insert and the concave shape of the inner diameter of the housing into which it fits. ligning angle ligning angle Fig.. llowable aligning angle of ball bearing units

8 tructure and Features uperior sealing performance FYH all earing Units efficiently prevent grease from leaking out of the interior of the bearing, and perform extremely well at keeping contaminates, such as dust and water, from entering. This is achieved by installing the seal to the outer ring of the bearing and installing the slinger to the inner ring of the bearing. The Floack seal to be used in the standard FYH all earing units will contribute to the long life of the bearing. It consists of a double-lip seal which is stamped into place in the outer ring of the bearing to reduce the possibility of being pushed out from over-lubrication. The first seal makes contact with the inside of the slinger which provides the first line of defense against contamination. The next seal makes contact with the inner ring to provide another level of contamination resistance. n additional level of protection exists in the extra non-contact inward facing lip which allows grease to flow back towards the balls and raceways during operation thereby improving lubrication performance and extending bearing life. llowable rotating speed is the same as the previous seal design while providing more than four times better protection. 4 imple lubrication FYH all earing Units are tapped to accept a grease fitting which is also supplied with every mounted unit. earings are pre-lubricated at the factory and do not require additional grease upon installation. When operating in excessively moist, dusty, or hot environments, it is recoended that grease be supplied at regular intervals. If appropriately maintained, the rated life of the bearing can be extended. FYH Lithium earing Grease to be sealed in early bearing grease use are manufactured to accoodate a wide range of operating conditions. FYH Lithium earing Grease can be mixed with of former FYH earing grease as it will improve performance, corrosion resistance, loading capability, and promote longer bearing life. The grease fittings that are supplied with FYH mounted units include - for smaller units and PT for larger units. dditional styles are available upon request. FYH Lithium earing Grease is also available in automatic lubricators. Floack eal Fig.. ealing mechanism of ball bearing units

9 Highly rigid and rugged cast iron housings FYH all earing Unit housings are designed so that they are optimized for reduction of deformation due to centralization of stress and load. Only the best material is selected to be cast by a highly advanced technique or press working technique, depending on the housing. ince any abnormal load on the bearing is eliminated by the housing, the life of the bearing can be extended. Granular material baking finish coating (powder coating) helps resist corrosion and protect the surface of the housing for an extended period of time. FYH original solid base pillow block housings seat better and produce a more stable mounting configuration that significantly reduces vibration. The support ribs have been eliminated to make more room for mounting bolts and washers, yet these housings are more than % stronger than before while also reducing housing weight. The new housing downward destruction strength means that the inserts break before the housings. eries and models FYH all earing Units are available in various series and models. Reliability of machinery or equipment, used together with these units, can be improved by selecting and using units optimal for the application and operating conditions. $High / Low Temperature eries $Corrosion Resistant eries tainless Units Plastic Units Nickel plated Units $ir Handling eries & earing Units NU-LOC Units $Dust Resistant Units Triple lip seal inserts Felt seal inserts $Dirt Resistant Units Tight Triple lip seal inserts Units with Covers imple installation and handling FYH all earing Units interchange with many different models and can be bolted to machinery without any modification. The exact amount of clearance is allowed between the bore and the shaft to allow a perfect fit. Therefore, FYH all earing Units do not require any additional lubrication or seal installation. s a result, handling and downtime can be drastically reduced. Four different locking mechanisms are available: $Tougher casting eries Ductile iron housing $Compact and lightweight eries mall die cast Units Lightweight casting Units tamped Units () et crew () Eccentric Locking Collar () Tapered dapter (4) Concentric Collar Mounting the bearing to the shaft can be executed easily and securely by adopting any of these methods.

13 .. Rotational speed adjustment due to shaft fit marginal degree of clearance is typically used to facilitate easy installation of a bearing to a shaft. The amount of clearance between the bearing and shaft must be factored in to determine the maximum allowable rotational speed, and as rotational speed is increased, the amount of clearance must be decreased. Table. shows the factor that must be used to correct the allowable rotational speed. The maximum rotational speed is determined by multiplying the speed found in Table. by the factors below. Table. Fitting factor of ball bearing units f c (recoended) Type of ball bearing units Heat resistant type (uffix code: DK) Cold resistant type (uffix code: DK) Fitting factor f c haft tolerance range class h, j j h h h h.... Operating temperature range The operating temperature of a ball bearing unit depends on the type of grease, the material of the seal, and the internal clearance of the bearing. FYH all earing Units are available in high temperature (DK, DK) and low temperature (DK) series, in addition to the standard models, to allow selection of the correct bearing for your operational temperature (see Table.). The correct unit must be chosen for the desired temperature range, and it is equally important to use the appropriate grease according to the specified schedule...4 Operating temperature and internal clearance of bearings When bearings are operated in a high ambient temperature environment, or when the operating temperature is high because of rotational speed, differential expansion rates occur within the bearing components. This causes higher friction, grease breakdown, and eventual seizure. If the temperature difference between the inner and outer ring is known, or can be approximated, then the following Formula (.) may be applied. Under these conditions, decrease in the internal clearance must be calculated, and the internal clearance of bearing needs to be selected properly... Correction of basic load rating due to temperature If a ball bearing unit is used at a relatively high temperature the physical composition of the bearing material is changed leading to decreased hardness. This decreased hardness leads to the basic dynamic load rating being reduced. Once the structure of the bearing material has been changed, it will remain this way for the life of the unit, even when it returns to room temperature. When using a ball bearing unit at ºC or more, the basic load rating must be corrected by multiplying the basic dynamic load rating shown in the dimensional table by the temperature factor shown in Table.4.

C is smaller clearance than the standard, and it reduces the noise and vibration in high speed applications. P is the suffix code that designates smaller bore tolerance which allows for a tighter fit with the shaft. This, in turn, reduces vibration and noise and dramatically increases bearing life. Non contact lip seal is available for the lighter torque.

16 election Guide.4. Features of the air handring units The air handling unit is manufactured with original fitting called the air handling fit which exists in the middle with fitting H which can be assembled more easily than a standard fit J. In addition, J fit the standard is fit that there is not the need for the anti-rotation pin, but can be very secure in high speed applications by adding the anti-rotation pin. and bearings are sound tested in order to make sure the noise level is low enough to be suitable for high speed applications such as blowers..4.

17 DUT DIRT. Dust Resistant Units The FYH Dust Resistant Units consists of a variety of supplemental sealing options that function extremely well in the exclusion of foreign matter. These options can work well by themselves or in combination with each other. From food processing and agricultural to wash-down and mining and aggregate, the FYH Dust From food processing and agricultural to wash-down and mining and aggregate, the FYH Dust Resistant Units can stand up to the toughest contamination challenges. Triple-Lip eals (suffix code: L) The L seal consists of a stamped steel shield with a molded NR try-ply seal affixed to the inner portion of the shield, all of which is attached to the outer ring of the bearing. The triple-lip seal is excellent for resisting all types of contamination and is appropriate for low to moderate speeds. Tight Triple-Lip eals (suffix code: LT) The LT Triple-Lip seal fits tighter than the standard L seal. The rotating torque of the LT seal is approximately double that of the standard L seal, and it is appropriate where contamination or moisture are very high and rotating speeds are very low.

18 election Guide tamped steel and cast iron covers are available in open or closed versions in a complete range of sizes. They are easy to install and they offer great resistance to wet and dry contaminates, and shocks and heats. Covers protect the entire bearing insert from contamination and they also help to provide a safer working environment. tamped teel Open Covers Cast Iron Open Covers CKIDE GURD The nitrile rubber shields can be mounted on the backside of two and four bolt flange units and the equipment it is bolted onto. The backside guard protects your bearings from dust and moisture and help lead to longer bearing life in applications where this can be an issue. The nitrile rubber on the steel plate come without a drain slot and is designed for dust protection. ome applications where this product could be used include: aggregate applications, fertilizer spreaders, salt spreaders and agricultural applications where dirt can reach the backside of bearing units. The nitrile rubber on the 4 stainless steel plate with the drain slot is designed to protect your bearing units in applications that are exposed to moisture and where moisture or water build up can create issues. These backside guards can be utilized in food and beverage applications where they are being washed down as well as pharmaceutical applications. The stainless steel core is perfect for situations where regular steel can rust quickly.

19 ORIGINL DEIGNED ET CREW ULLET POINT The innovative FYH ullet Point set screw is a one piece ball point set screw which is designed to expand the threads of the screw as the point of the screw contacts the surface of the shaft.the resulting force creates superior holding power especially where vibration is present. Other set screws have larger contact areas with sharp edges at the point of the screw to bite into the shaft. However, these sharp edges damage more easily from vibration which creates a gap between the point of the set screw and the shaft. Once this gap is established, the set screw will begin to loosen. When the ullet Point set screw is tightened, the original shape of the point causes the threads of the screw to expand up to and beyond the elastic limit to achieve the maximum possible holding power. The thickness of the point is also designed to expand easily. This specialized design drastically reduces the potential for damage to both the set screw and shaft from normal use or for severe vibration, shock load, and high speed. Tightening Torque Expands Outward HFT CONTCT TRUE Concentric-LOC The FYH NU-LOC bearing grips the shaft more uniformly, which allows for degrees of equalized locking contact. Compared to set screw bearings, the roundness of the ball path on the NU-LOC bearings results in better operation and longer life. NU-LOC concentric locking collars are designed to prevent shafting from becoming marred or burred. single standard hex head cap screw can be tightened quickly and easily, and NU-LOC bearings can replace either setscrew or eccentric locking collar inserts. NU-LOC concentric locking collar with a single cap screw provides excellent holding power. The collar is installed over the slotted inner ring on the shaft concentrically. Quick & Easy Installation with a single hex cap screw. NU-LOC s standard tolerance specification is designed for air handring applications, and the greater roundness of the ball path enable the use of smaller internal ball clearance. The bore tolerance is also smaller since NU-LOC has the degrees of equalized locking contact. NU-LOC is not only good for the air handring applications, but great for the other applications as well.

35 4 Rating Life of earings When ball bearing units are installed and operated on a piece of machinery eventually a failure will occur. The period of operation until the unit cannot be used due to failure is called the bearing life. earing failure is caused by two main reasons. The first is fatigue of bearing material, and the second is lubricant degradation. The life is figured on whichever fails first. Proper bearing lubrication will eliminate grease degradation and allow full bearing life to be achieved. If the bearing units are run without replenishment of the grease the bearing life will have to be factored by either the grease life or the bearing life. During installation, care must be taken not to damage the bearing. Proper bearing maintenance and lubrication will ensure long bearing life. 4. asic Rating Life and asic Load Rating 4.. asic rating life When a bearing is rotated under load the raceways and the rolling elements are continuously exposed to load. Damage, such as scaling (flaking or peeling), eventually appears on the material, and the total rotating frequency until the damage appears is called the fatigue limit of the bearing. Fatigue limit of the bearing can vary greatly even if the bearings have the same structure, dimensions, materials, machining methods, and are operated under the same conditions. To account for this variation, a group of the same bearings operating under the same conditions are tested, and the total rotating frequency of % of the bearings operating with no damage due to rotating fatigue (% reliability) is called the basic load rating. 4.. asic load rating Dynamic ratings are determined by placing a pure radial load on a radial bearing or by placing a central axial load on a thrust bearing. The dynamic rating is the load that the bearing will withstand for one million cycles before failure of the bearing. These ratings are referred to as the basic dynamic radial load rating (Cr) or the basic dynamic axial load rating (Ca). These values are indicated in the catalog as the basic dynamic radial load rating (Cr), and the value is shown in the dimensional table. 4. Calculation of Rating Life The relationship between the basic rating life, the basic dynamic load rating, and the dynamic equivalent load of the ball bearing is indicated in Formula (4.). If the ball bearing unit is being used at a fixed rotating speed, the life is indicated as time. This is shown in Formula (4.).

36 4 Rating Life of earings 4.. Correction of basic load rating due to temperature If a ball bearing unit is used at a relatively high temperature the physical composition of the bearing material is changed leading to decreased hardness. This decreased hardness leads to the basic dynamic load rating being reduced. Once the structure of the bearing material has been changed, it will remain this way for the life of the unit, even when it returns to room temperature. When using a ball bearing unit at ºC or more, the basic load rating must be corrected by multiplying the basic dynamic load rating shown in the dimensional table by the temperature factor shown in Table 4.. Table 4. Temperature factor earing temperature, ºC Temperature factor Corrected rating life The basic L rating life shown in Formula (4.) is the fatigue life of a bearing with % reliability however; there are circumstances where bearings need greater reliability. The bearing life may be extended by using special materials. Other conditions, including lubrication, may influence the bearing life. The corrected rating life is found by taking the basic rating life and taking the factors in Formula (4.) into consideration. Lna = a a a L (4.)

Factors that can influence the bearing include bearing material (type of steel), production procedures, and bearing design. earing characterization is shown as factor a. FYH ball bearing inserts use high quality vacuum degassed bearing steel as standard material, and this material allows for a longer rating life. For FYH ball bearing units, the bearing characterization factor a is (a = ). When bearings with special materials are used for a longer fatigue limit the characterization factor can be shown as a being greater than (a > ). () Operating condition factor a Operating conditions may directly influence the life of the bearing (especially proper or improper lubrication). The basic rating life should be corrected using the operating condition factor a. If lubrication is being maintained the factor a =. If excellent re-lubrication practices are being maintained the factor a > should be applied. If any of the following operating conditions are applicable the condition should be applied as a <.

In addition to the primary load, other resultant loads include the weight of complementary objects including shafting, gears, pulleys, torsion from chain and belts, and so on. hock or dynamic load can also be derived from these sources. In many cases, these loads cannot be determined by a simple or single calculation; and since these loads often fluctuate in intensity, it is difficult to determine the exact magnitude of them prior to actual lab or field measurements on the machinery in question. However, in order to approximate the loads involved prior to putting a machine into operation, the technique shown below should be used.

Use the load factors shown in Table. to account for vibration and impact. standard radial ball bearing bears an axial load component in addition to the radial component.

Distribution of load to bearings. Dynamic Equivalent Load In many cases, a bearing is exposed to the combined vector load of both radial and axial load components. It may also be used under more severe conditions such as vibration and shock load. In this case, a direct comparison to the dynamic load rating is not appropriate. In such a case, find the load equivalent to a direct radial load only and compare this with the basic dynamic load rating. The converted virtual load is called dynamic equivalent load (P)... Calculation of dynamic equivalent load The dynamic equivalent radial load (Pr) of a bearing that bears radial and axial loads as well as vibration and impact is found by the following formula. Pr = XFr + YFa (.) Whereas, Pr: Dynamic equivalent radial load, N Fr: Radial load, N Fa: xial load, N X: Radial load factor (see Table.4) Y: xial load factor (see Table.4)

When the bearing reaches the speed limits shown below, it will seize if operated continuously at these levels. The limiting rotational speed is the maximum speed at which the bearing can be safely operated continuously. These allowable rotational speeds of a ball bearing unit are dependent upon the dimensions of the bearing, type of seal, and the fit of the bearing inner ring to the shaft.

49 . Rotational peed djustment Due to haft Fit marginal degree of clearance is typically used to facilitate easy installation of a bearing to a shaft. The amount of clearance between the bearing and shaft must be factored in to determine the maximum allowable rotational speed, and as rotational speed is increased, the amount of clearance must be decreased. Table. shows the factor that must be used to correct the allowable rotational speed. The maximum rotational speed is determined by multiplying the speed found in Table. by the factors below. This table includes the multiplying factors for set screw bearings as well as bearings with adapters and eccentric locking collars. Due to the characteristics of bearings with adapters, a loose fit, h or h, is acceptable. earings with eccentric locking collars function optimally with less clearance and therefore, an h or j fit is recoended to achieve the maximum allowable speed.

With adapters With eccentric locking collar NU concentric locking collar Operating Temperature and earing pecifications. Operating Temperature Range The operating temperature of a ball bearing unit depends on the type of grease, the material of the seal, and the internal clearance of the bearing. FYH all earing Units are available in high temperature (DK, DK) and low temperature (DK) series, in addition to the standard models, to allow selection of the correct bearing for your operational temperature (see Table.). The correct unit must be chosen for the desired temperature range, and it is equally important to use the appropriate grease according to the specified schedule.. Operating Temperature and Internal Clearance of earings When bearings are operated in a high ambient temperature environment, or when the operating temperature is high because of rotational speed, differential expansion rates occur within the bearing components. This causes higher friction, grease breakdown, and eventual seizure. If the temperature difference between the inner and outer ring is known, or can be approximated, then the following Formula (.) may be applied. Under these conditions, decrease in the internal clearance must be calculated, and the internal clearance of bearing needs to be selected properly. t = α De t (.) Whereas, t: Decrease in the internal clearance of bearings depending on the difference in the temperatures of the bearing inner ring and the bearing outer ring can be found by formula, α: Line expansion factor of bearing steel,.

50 trength of Housings trength of Housings FYH bearings can withstand very high loads due to the use of only high quality material and excellent design. However, when high static or impact loads are encountered, the load capacity of the bearing must be determined. The housing design is such that it can withstand loads from any angle; however the bearing is strongest with a direct downward load through the base of the unit. For loads in other directions, the allowable load must be determined specifically for the direction in question. Rigidity of the base and flatness of the mounting surface also influence the housing strength. The equipment designer or installer must examine and perform calculations for the complete supporting structure of the bearing.. trength of Cast Iron Housings lthough gray cast iron has many superior characteristics, it may fail under impact loads, particularly in a low temperature environment.

58 Design of haft and ase Design of haft and ase. Design of haft For optimal performance of a ball bearing unit, and for maintenance-free operation for an extended period of time, proper shaft selection is very important. The shaft should be straight, of sufficient tensile strength, and free of burrs and scratches... Dimensional accuracy of shaft () Dimensional tolerance of shaft used for set screw bearings For bearings with set screws, a relatively looser class of fit makes assembly easier and is perfectly acceptable at low operating speeds. The clearance between the bore of the bearing and the shaft must be decreased as the rotational speed is increased. Table. shows the guidelines for the tolerance class for the rotational speed of bearings with set screws. If the bearing with set screws is exposed to a heavy load (Pr / Cr >.), vibration, or heavy impact, use a tighter shaft tolerance than normal. Table. shows the tolerances for tight fits.

60 Design of haft and ase.. High temperature applications In general, two bearing units are used per shaft. If the distance between the bearings is small, or if the temperature change of the shaft is small, both bearings may be fixed in position. However, if the distance between the bearings is large and the shaft is exposed to heat, then only one bearing should be fixed and the opposing bearing must be free to float in the axial direction. This is because shaft expansion due to temperature change of the shaft causes a high axial load and can cause failure of fixed bearings. The amount of shaft expansion due to temperature change may be calculated by using Formula (.). = α t l (.) Whereas, : Expansion of shaft, α: Linear expansion coefficient of shaft in the case of ordinary steel, ~ t: Temperature increase, ºC l: Installation distance of unit, Proper installation procedures for a shaft exposed to temperature changes are shown below. () Installation with a dog point set screw on the free side To accoodate shaft expansion in the axial direction, the bearing must be installed so that the shaft can move freely through the bore in either axial direction. To accomplish this, the shaft must be grooved for a full dog point set screw (suffix code: G). This should be done on the free side only. The dog point screw allows free movement in the axial direction and provides force to rotate the bearing in the radial direction. Fig.. shows an example of the structure of a bearing with a key groove on the shaft and a full dog point set screw. Table. shows the dimensions of the key groove for the full dog point set screw. Note that the full dog point set screw in the image is also capped so that it may be tightened against the bearing, not the shaft. full dog point set screw with a jam nut will also work to achieve this function. The tolerance class of the shaft to be used is h. If the temperature of the shaft is higher than that of the bearing, then a looser fit tolerance class is specified. When using this method to allow for free expansion, there is the possibility of fretting between the shaft and the inner race. In order to prevent fretting, a high temperature grease must be applied to the inner ring of the bearing and the shaft prior to installation. Full dog point set screw Fig..

61 () Installation of cartridge type units on the free side If the rotational speed is high or if the bearing is exposed to high vibration, the cartridge type unit is recoended on the free side. In this case, the housing of the cartridge unit is free to move axially within the mounting bore and the bearing insert is rigidly attached to the shaft. Fig.. shows the required structure for the cartridge type unit on the free side... Mounting cartridge type units in high temperature applications Cartridge units are designed to fit into an accurately bored cylindrical opening in the mounting base. Under ordinary operating conditions, H is an adequate choice for the tolerance class of the cylindrically bored hole. In instances where both the bearing and the shaft are heated during operation, select G as the tolerance class of the cylindrical bore. If the bearing is exposed to excessive vibration or impact, then an even tighter tolerance class must be specified. Table. shows the dimensional requirements for the cylindrical bore. Table. Dimensional tolerance of cylindrical bore for mounting cartridge type units (recoended values) Unit: μm Fig.. Use of cartridge type units on free side If, in addition to the expansion of the shaft, the ball bearing itself is exposed to heat, then a calculation of the decrease in internal clearances of the bearing must be made. The appropriate bearing internal clearance must be specified. (see Operating temperature and bearing specifications ).. Mounting ase Design.. Rigidity of base and flatness of mounting urface If rigidity of the base on which a ball bearing unit is to be mounted is not sufficient, or if the flatness of the mounting surface is poor, then vibration or abnormal noise may occur during operation. This may lead to premature bearing failure since the strength of the housing is diminished from improper support. The mounting surface must be accurately machined to eliminate deformation of the housing.

69 . Internal earing Clearance Internal bearing clearance is defined as the allowable space between the bearing balls and the raceways. The degree of internal clearance, referred to as operation clearance, greatly influences operational life of the bearing as well as characteristics of heat, noise, and vibration. If the clearance is exceptionally tight between the shaft and the inner ring of the bearing then expansion of the inner ring must be taken into consideration and the correct ball clearance should be selected. Transmission heat from the shaft is also a factor to consider when determining the correct amount of ball clearance (see Operating temperature and bearing specifications ). Table. shows the internal clearance applicable to specific operating conditions and Table. shows the available options for internal clearance. Table.

70 Materials Materials. earing Material all bearing inserts are comprised of inner and outer rings, balls, and steel ball cages all of which are made from the highest quality of bearing steel. These bearings possess the following features. () High elastic limit to resist strong opposing force () High rolling fatigue strength to allow for heavy loads () uperior hardness (4) uperior wear resistance () uperior toughness against impact and shock loads () uperior precision of dimensional tolerances High carbon chrome bearing steel is utilized for the bearing components as specified in JI (Japanese Industrial tandards). To increase reliability and reduce contamination within the material, a vacuum degassing process is executed to reduce non-metallic elements and any oxygen in the steel. fter the bearing is assembled it is heat tempered and quenched until the hardness reaches HRC. Table. shows the chemical components of high carbon chrome bearing steel. tainless steel bearing inserts (suffix: ) utilize superior corrosion resistant JI certified stainless steel. Riveted steel ball cages are made of JI certified cold rolled steel which is shown in Table... Housing Material FYH housings are made primarily of gray cast iron, and stamped steel. Gray cast iron is the most popular choice for mounted units because of its optimal characteristics of vibration absorption, high strength, and excellent heat dissipation. Table. shows the mechanical properties of gray cast iron (FC). Nodular graphite cast iron, or ductile iron, (FCD4- of JI G ) provides a good combination of rigidity and fracture resistance, and it is suitable where heavy vibration or impact forces are present. Housings for units within the Clean eries are available in die-cast zinc alloy as well as stainless steel. Housing material for stamped steel units consists of thick gauge cold rolled sheet steel and steel strip. Table.4 to. show the mechanical properties of these housing materials. Table.

72 Performance Performance. earing Friction Torque earing friction torque is the conglomeration of the rolling friction between the balls with the inner and outer rings, the sliding friction between the balls and the cage, the agitating resistance of lubricants, and the friction resistance of the seals. The specific amount of friction torque is influenced by the particular bearing model, dimensions, bearing load, rotating speed, and lubricating conditions. earings with triple-lip seals and open cover seals will have greater friction torque and overall greater friction resistance. Friction torque for bearings can be found by the formulas below. M = Mp + Mk (.) d Mp = l P (.) Whereas, M: Friction torque of bearing, mn m M p : Friction torque of sections changed by load, mn m M k : Friction torque of sections changed by rotating speed, mn m l: Friction coefficient (. to.) P: Load applied to bearings, N d: Nominal bearing bore dia., Note that the agitating resistance of lubricants and the friction resistance of the seals are difficult to calculate since the resistance fluctuates with speed. Fig.. shows the result of measurement of friction torque of the typical ball bearing unit.. earing Temperature Increase The increase in temperature of the bearing is represented as heat energy created from friction torque in the bearing during operation. The temperature of the bearing during operation increases in proportion to the amount of friction torque, and friction torque increases in proportion to the increase in bearing load. The increase in temperature of the bearing depends on the heating value generated by friction in the bearing and the amount of heat discharged from the bearing and housing in which it is mounted. Therefore, the temperature level of the bearing is influenced by the environmental conditions of the location in which the bearing unit is installed (quality of heat radiation environment). The operating temperature of the bearing unit increases gradually after startup of operation and reaches the maximum level after one or two hours if no abnormalities occur. Then it decreases slightly and enters a steady state (see Fig..). If the operating conditions are not changed, bearing temperature will remain virtually constant, and measurement of the temperature and assumption of the bearing status are enabled. Increase in temperature ºC Pillow type unit UCPJ Rotating speed:, min Radial load kn Radial load kn Friction torque mn á m 4 UC UC UC4 t startup,,,, Rotating speed, min Fig.. Example of measurement result of ball bearing units Operating period hr Fig.. Example of temperature measurement during operation of pillow type units Increase in temperature during operation of the bearing depends on the type of seal used in the bearing as well as friction torque. Increase in temperature of triple-lip bearings (suffix code: L) is greater than that of the standard single lip model, and that of the non-contact seal (suffix code: K, ) is lower than the standard single lip model. earings for blowers and other high-speed applications are equipped with non-contact seals, with grease or oil, for high-speed operation as well as reduction of heat, vibration, and noise.

73 4 Handling 4. Installation Table 4. et screws of ball bearings for units 4.. Installation of setscrew units When installing setscrew units, it is important to tighten the setscrews to the shaft with the specified torque. When the clearance between the inner ring and the shaft is small, then grind the surface of the shaft where the setscrew contacts and make a flat base (Fig. 4.). It helps you to take the shaft out of the inner ring. Fig. 4. Flat seat provided for shaft If the unit is exposed to great load or excessive vibration, another option is to use a shouldered shaft and tighten the inner ring of the bearing with a shaft nut. (Fig. 4.) For dimensions of the shouldered shaft, see Design of shaft and base. houldered shaft haft nut Fig. 4. Example of installation with a shouldered shaft and shaft nut FYH earings are available with a variety of set screw options including Double Point and ullet Point set screws which provide a secure fit to the shaft. dditional styles of setscrews are also available to meet a range of purposes and operating conditions (see Table 4.). Designations (code) ullet Point ULLET POINT Double Point (G) Cone Point (G4) Capped Full Dog Point (G) Details The tip of the FYH ullet Point setscrew has a ball shape, and it is designed to fi rmly grip the shaft by expanding its threads outward against the threads of the inner ring of the bearing as it is tightened. When shock or vibration are problems, the ullet Point setscrew can remain affi xed to the shaft longer than other set screw styles including double point, ball point, or others. The cone point at the center of the screw, combined with the round point at the outer edge, provide excellent shaft contact and greatly reduced fi tting error. This style is also available with a nylon fi lm fused to the thread surface to prevent the screw from loosening during operation. The cone point setscrew has a º angle and fi ts a drilled cone seat in the shaft. It allows correct positioning on the shaft and prevents shaft movement in an axial direction. (Fig4.) The capped full dog point setscrew fi ts into the keyed groove in the shaft and allows for expansion and contraction of the shaft. It tightens to the inner ring of the bearing (not the shaft) to allow the shaft to fl oat within the bore of the bearing. When correct positioning is required, make a drilled cone base on the shaft, and tighten the shaft, using a cone point set screw (Fig. 4.). Fig. 4. Drilled seat provided for shaft

74 4 Handling Contact FYH for additional set screw styles. hown below are installation procedures for bearing units with setscrews. () Inspect the unit to ensure that the rigidity of the base, flatness of the mounting surface, and tolerance of the shaft meet the required standards. Check the shaft for bends, burrs, and other flaws. () Make sure that the set screws are retracted far enough so that they do not contact the shaft as the bearing is installed. () Fit the bearing unit onto the shaft and slide it to the specified position. In order to secure a tight fit, press-fit the bearing unit to the shaft with a press, cold-fit by cooling the shaft, or shrink-fit the bearing unit by warming it with an air bath ( ºC or less). void striking the bearing with a haer to press-fit the bearing to the shaft. If you give a strong impact to the side surface of the inner ring, the both slinger moves, and it may cause a problem. (4) lign the bearing unit to the specified position on the base and affix it with washers and bolts. (Fig. 4.4). Use a torque wrench to tighten the bolts to the housing to the specified torque setting. For mounting bolt torque specifications, see ppendix table in the back of the catalog. () Finally, turn the shaft by hand and make sure that it rotates without any problems. 4.. Installation of adapter style units dapter units, comprised of an adapter sleeve, locknut, and washer, can be installed into environments where they are exposed to excessive vibration and impact. It is of great importance that these units are properly mounted. If the locknut is not properly tightened, the sleeve may be loose which could lead to slippage and wear on the shaft or bearing. Conversely, if the locknut is over-tightened, the inner ring of the bearing can expand and reduce internal ball clearance which could cause excessive heat and premature failure. Installation procedures for adapter style bearings are shown below. () Inspect the unit to ensure that the rigidity of the base, flatness of the mounting surface, and tolerance of the shaft meet the required standards. Check the shaft for bends, burrs, and other flaws. () lide the adapter sleeve onto the shaft where the bearing unit will be installed. If the sleeve is too tight, place a screwdriver in the slotted portion of the sleeve and expand the slot to open the sleeve. () lide the bearing unit over the shaft and onto the adapter sleeve, then place a cylindrical reinforcing ring against the inner ring of the front side of the bearing. eat the adapter sleeve by lightly tapping all around the backside of the sleeve (Fig. 4.). Reinforcing plate Fig. 4.4 Installation of setscrew units () Tighten both of the setscrews on the inner ring to the specified torque setting (Fig. 4.). For setscrew torque specifications, see ppendix table in the back of the catalog. Fig. 4. Fitting adapter sleeve to bearing with tapered bore (4) ttach the lock washer so that the tab fits into the slot in the sleeve, and, making sure the tapered side is facing the bearing, tighten the locknut on the sleeve by hand. () lign the bearing unit to the specified position on the base and affix it with washers, and bolts. Use a torque wrench to tighten the bolts to the housing to the specified torque setting. For mounting bolt torque specifications, see ppendix table in the back of the catalog. () Use a torque wrench to tighten the locknut to the correct specification (Fig. 4.). For locknut torque specifications, see ppendix table 4 in the back of the catalog. Fig. 4. Tightening of set screws () Turn the shaft by hand and tighten the setscrews of all other bearings on the same shaft to the specified torque setting.

75 ince the rotating force of the shaft increases the tightening force of the eccentric ring to the shaft, the unit with eccentric locking collar allows secure fixing of the bearing (Fig. 4.). Fig. 4. Tightening locknut () For pillow block housings, loosen the mounting bolts and adjust the unit axially while rotating the shaft by hand. Then re-tighten the mounting bolts to the correct specification. () For flange block housings, the position of the unit must be in the correct axial position in relation to the shaft, so take extra care to properly align them before completing installation. () end one of the tabs on the washer so that it fits into one of the slots on the locknut (Fig. 4.). Fig. 4. all bearing units with eccentric locking collar Installation procedures for eccentric locking collar style bearings are shown below. () Inspect the unit to ensure that the rigidity of the base, flatness of the mounting surface, and tolerance of the shaft meet the required standards. Check the shaft for bends, burrs, and other flaws. () lide the bearing unit onto the shaft, and place it at the specified mounting position. () lign the bearing unit to the specified position on the base and affix it with washers, and bolts. (Fig. 4.4). Use a torque wrench to tighten the bolts to the housing to the specified torque setting. For mounting bolt torque specifications, see ppendix table in the back of this catalog. (4) Fit the eccentric section of the inner ring of the bearing to the eccentric recessed section of the eccentric locking collar, and rotate the collar in the direction of shaft rotation. Then, tighten the setscrew on the eccentric locking collar to the specified torque setting (Fig. 4.). Fig. 4. ending claw of washer (Locking locknut) () Finally, turn the shaft by hand and make sure that it rotates without any problems. 4.. Installation of units with eccentric locking collars Eccentric locking collar bearings provide another option for shaft locking. ince the rotating force of the shaft increases the tightening force of the eccentric ring to the shaft, this style of bearing allows a secure grip to the shaft. Fig. 4. Installing eccentric locking collar

76 4 Handling (4) The NU-LOC collar is tightened by a hexagon head bolt to a specified torque setting in order to apply the correct amount of force to the inner ring o the bearing. (Fig. 4.) Regarding tightening torque for set screws or hexagon head bolts, see ppendix Table in the back of this catalog. Pack grease Fig 4. Installation of NU-LOC units () Rotate the shaft by hand and then install the next eccentric locking collar unit to the shaft. () Finally, turn the shaft by hand and make sure that it rotates without any problems Installing units with covers Covers for ball bearing units are available in two types, steel plate and cast iron. Install both the covers at last after installation of the bearing and housing is complete. Procedures for installation of the ball bearing units with covers are shown below. () pply grease all around the seal lip of the cover, and pack the internal space of the cover with grease (approximately / to of the space capacity) (Fig. 4.). Fig. 4. Packing grease in internal space of seal lip of covers () Make sure that the bearing unit is securely fixed to the shaft and mounting base. () lide the cover over the shaft to the grove in the housing and lightly press it into place. (4) For stamped steel covers, use a plastic mallet to prevent deformation, and evenly tap all around the periphery of the cover to install it to the housing (Fig. 4.). To remove the stamped steel cover, put a screwdriver into the groove on the periphery of the cover and slightly pry it. Fig. 4. Installing steel plate covers 4

77 (4) When installing a cast iron cover, fit the cover to the cover groove of the housing, and affix it with the supplied bolts. For the tightening torque of the cast iron cover mounting bolts, see the ppendix table at the end of this catalog. () Install another cover to the housing in a similar manner. () Check for abnormality of the installed cover. () Finally, turn the shaft by hand, and check for abnormality in the bearing. 4. Test Run Inspection fter installation of the ball bearing unit is complete, execute the test run inspection to ensure that it was done properly. The test run inspection should be executed by following the procedures below. () Turn the shaft by hand and make sure that the bearing rotates smoothly. If there is any resistance, vibration, excessive rotational torque, or uneven rotation, the bearing is judged to be faulty. () Execute a powered run with no load and at low speed, and check for abnormal noise and vibration. () Execute a powered run under normal operating conditions and check for abnormal noise, vibration, and temperature increase. Table 4. shows the main faults that may occur during the test run inspection of the ball bearing unit and causes. Table 4.

Periodic Inspection FYH all earing Units do not need to be inspected as frequently as lower quality bearings. However, it is good practice to set up an inspection schedule for even these high quality bearings. ince a ball bearing unit cannot be disassembled for inspection of the internal status of components, the external appearance of the bearing must be inspected to give tell-tale signs of the status and expected life of the bearing. The following characteristics must be checked per the inspection schedule that is established for a particular application. () Overall appearance () Loose set screws or mounting bolts () Noise from vibration (4) Temperature of the bearing housing or the inner ring () Grease supply interval and quantity of grease injected into the bearing (either too much or too little grease can be detrimental to the life of the bearing) Table 4. shows the main faults that are usually found during periodic inspections and their causes. If any fault is found in a ball bearing unit during an inspection, then iediate action must be taken to correct the situation and prevent deterioration of the bearing components. If serious damage has already occurred to the bearing unit, then the bearing unit must be replaced iediately to prevent damage to other machine components. Table 4. Faults Excessive torque bnormal noise, abnormal vibration bnormal temperature increase Main faults found during periodic inspection and their causes Causes () Degraded grease () Interference of seal with slinger due to excessive supply of grease () Deformation of slinger causing interference with seal (4) High load due to shaft expansion () Improper tightening of set screws locknut (adapter) or of mounting bolts () Wear on inner ring of bearing or shaft due to creep or fretting () Ingress of foreign matter (dirt) into bearing (4) Damage to cage or ball surfaces due to rolling fatigue () Indentation on raceway surface or ball surface due to excessive load () Warped or bent shaft () Degraded grease () Interference of seal with slinger due to excessive supply of grease () Deformation of slinger causing interference with seal (4) Looseness of setscrew, eccentric locking collar or adapter lock nut for tapered bore bearings () Load due to shaft expansion () Damage to cage or ball surfaces due to rolling fatigue

78 4 Handling 4.4 upply of Grease FYH all earing units are supplied with high quality FYH Lithium earing grease and seals. Therefore, under clean operating conditions, light loads, low speeds, and low temperatures the bearing may be used with no further lubrication. However, under harsher operating conditions and environments, the grease will deteriorate much more rapidly. This would include environments exposed to dust, moisture, or higher operating temperatures. In such cases, a re-greasing schedule must be established to prevent premature failure of the bearing. The life of the bearing can be greatly extended by proper attention to the re-greasing schedule and by supplying the proper amount of grease. Please note that too much grease can be detrimental as well as too little grease Grease life and supply intervals The grease life of a bearing unit can be found using Formula (4.) in page. The re-greasing schedule should be set at to / of the grease life found by the calculation shown above; however this may be adjusted for particularly demanding environments or conditions. In addition, some environments may be unusually dirty or wet, and these conditions may be exacerbated by higher temperatures. Under such harsh conditions, a more frequent re-greasing schedule will extend the life of the bearing. Under normal operating conditions, adhere to the guidelines outlined in Table. in page mount of grease The amount of grease initially supplied in a new FYH all earing Unit is approximately to % of the internal space capacity of the bearing. If the bearing is over greased, the agitation of the grease causes internal friction and heating of the bearing. The first sign of failure will be excessive grease finding its way to the outside of the bearing. DO NOT exceed the initial greasing amount. Table 4.4 shows the recoended amount of grease to be used for re-greasing FYH bearings. In a severely dusty or wet environments, the amount of grease may be as much as doubled if operating speeds are low. Table 4.4 mount of recoended grease for ball bearing units ore dia. code... Greasing amount, g Diameter eries ) UC UCX UC The basic bearing size number consists of the duty code (, X, or ) followed by the inner ring size code (,, 4, etc.) Note:. Table 4.4 applies to UK units as well.. For greasing triple-lip (L) type bearings, use times the amount of grease recoended in the table.. Values shown in the table are applicable to standard grease (density:. g/ml). If a compatible grease of another specific gravity is used, then the proper conversion must be made to insure that the recoended volume is put into the bearing.

79 4.4. Types of grease supplied Many different types of grease are available for use in ball bearings. However, if a non-compatible grease is used, particularly a non-lithium based grease, then performance may be drastically reduced. Only use the grease recoended in Table. (page ) to assure optimum performance of your bearings. If another grease is used in an emergency situation, for instance, please assure that this grease is compatible, with a lithium base, at the minimum. If it is difficult to access the standard straight type grease fitting with a grease gun,.º and º angled fittings are available as an option. ee the images below of these grease fittings. Contact FYH for more information.

Types of grease fittings for ball bearing units When using a centralized automatic lubrication system, with ball bearings, it is important to use softer grease than normal. The grease should be specified with a worked penetration number between and. This is NLGI grade or. Piping from the lubricating system must be sized so that the specified volume of grease is supplied. Piping must be connected to the threaded hole on the ball bearing unit. This is either - tapered threads for units up to and including ring size, or PT (PT) for ball bearing units with a ring size and larger. If the piping size used is larger than the threaded hole in the ball bearing unit, then the appropriate reducing coupling (or street elbow) must be used to fit the threaded hole. Fig. 4. shows the body of a pipe reducer. When using an automatic centralized lubrication system, it is imperative to assure that the correct volume of grease is supplied to each individual bearing as specified in Table 4.4. The total amount of grease is a multiple of the number of bearings being supplied by the central lubrication system. Fig. 4.4 upplying grease to ball bearing units () Clean the grease fitting and the area around it to prevent dirt and foreign material from entering the unit. () Clean the grease gun and pack clean grease. () Grease the unit with the recoended amount of grease. When lubricating the ball bearing unit, slowly turn the shaft with your hand. This allows the fresh grease to be uniformly distributed inside the unit. Fig. 4. Reducing coupling for centralized lubrication systems

80 4 Handling 4. Replacing earings If a bearing insert needs to be replaced, it is not always necessary to replace the housing if the housing is intact. fter carefully inspecting the housing to ensure that it is not damaged, simply insert a new bearing into the old housing. Replacement procedures for a bearing insert are listed below. () Remove the complete bearing unit from the shaft and mounting base. () crew in the set screws so that the head of each set screw does not protrude outside the outer diameter of the inner ring. Otherwise, the head of the set screw may damage the bearing seat inside the housing. () Use a bar or pipe to rotate the bearing º until the bearing is horizontal. (4) Remove the bearing insert from the housing via the loading slot in the back of the housing. Reverse the above procedure to put in a new bearing insert. Ensure that the set screws are screwed in before proceeding with the replacement.

Models and Features PHERICL ROLLER ERING UNIT -olt ase Pillow lock Units XP XEP 4-olt Flange Units X4F XE4F Flange Cartridge Units X4FC ZP ZEP Z4F ZE4F Z4FC XP is a two-bolt pillow block unit with a setscrew locking insert system. This unit is equivalent to many of our competitors R style housings. XEP is with Type E mounting dimensions which has a footprint that can accoodate both a tapered roller unit and a spherical roller unit for most shaft sizes. ZP and ZEP have the same housing dimensions as the above styles but utilize our revolutionary Z-Lock concentric locking collar system. X4F is a four-bolt flange unit with set screw locking system. It has standard spherical roller unit mounting dimensions and a compact footprint for areas with limited space. XE4F has Type E mounting dimensions with the same footprint as a tapered roller unit. Z4F and ZE4F have the same housing dimensions as the above units but utilize our revolutionary Z-Lock concentric locking collar system. X4FC is a piloted flange cartridge unit with a setscrew locking insert system. Its pilot mounting dimensions are the same as the medium duty ball bearing units that allow for easy upgrades to a heavier duty series. The threaded withdrawal holes make for quick and easy dismounting. Z4FC carries as the same housing dimensions as the above unit but incorporate the revolutionary Z-Lock concentric locking collar system. 4 Take-Up Units XT is a take-up unit with set screw locking system. It has rail slots that are compatible with many industrial frame sizes. This unit can safely handle high belt tension and heavy shock loads.

216 Installation Guide Installation Guide. Precautions Read the entire installation guide prior to beginning. earings are precision instruments and they must always be handled carefully to prevent damage. tore bearings in a cool and dry location, and always leave bearings in original packaging until ready for installation. earing life calculations should be performed prior to installation to ensure that the selected unit is acceptable for the application. The use of more than two bearings on a single shaft is not recoended. To maximize the life of the bearing avoid mis-alignment and pre-loading by carefully following these instructions. lways lock out the power source and adhere closely to industry safety standards before performing any work on the equipment.. Preparation The mounting surface and housing base must be clean, flat, and of sufficient thickness to support the weight of the entire assembly without deflecting or breaking. Make sure that the mounting surface is parallel to the plane of the shaft for pillow blocks, and perpendicular to the shaft for flanges and take-up units. FYH mounted bearings can accoodate up to ± degrees of mis-alignment, however longer bearing life can be achieved if mis-alignment can be minimized during installation. Check the shaft diameter and make sure that it is within tolerance as indicated in Table. Check that the shaft is straight, clean, and free of burrs or other imperfections. Use emery cloth or a fine file to smooth the surface as necessary. small amount of lubricant may be applied to both the shaft and the bore of the bearing; however lubricant should not be applied to the areas where the bearing locking mechanism contacts the shaft. To ensure adequate locking power between the bearing and shaft the hardness of the shaft should not exceed Rc 4. haft ize () h Table - haft Tolerance haft peed Greater Than % of Max RPM Rating h haft peed Less Than % of Max RPM Rating Over Incl.

When ready for installation, slide the insert forward in the housing approximately one thirty-second of an inch ( ) and alternately tighten the set screws onto the shaft to the specified torque setting as shown in Table 4. fter bearing installation efore performing any work on the bearing, lock out the power source and allow the shaft and adjacent machinery to cool down to ambient temperature. Loosen the set screws or other locking mechanism to allow the shaft to move freely within the bore then follow the same procedures explained in the efore bearing installation section. 4

Expansion bearings should be installed only after the shaft and adjacent machinery has cooled down to the ambient temperature. fter positioning the expansion unit on the shaft slide the insert to the rearmost position within the housing until it seats against the retaining ring. Then slide the insert forward in the housing approximately one thirty second of an inch ( ) and alternately tighten the set screws onto the shaft to the specified torque setting as shown in Table. llowable shaft expansion and expansion calculation data can be found in Table 4 and Formula respectively..

218 Installation Guide.4 Lubrication Proper lubrication practices will greatly extend the life of the bearing. earings are factory lubricated with the proper amount and type of lubricant for most general purpose applications as well as many highly demanding operating environments, and except as recoended by FYH, no further lubrication is required upon installation. Lubrication tips: The factory standard lubricant is a Calcium ulfonate grease. lways use the same type of lubricant to avoid compatibility issues and other potential problems. When adding lubricant do so slowly and while the bearing is rotating until a small amount of lubricant can be seen coming out of the seals. t low speeds (below RPM) it is acceptable to completely fill the bearing with grease. t moderate to high speeds it is not advisable to completely fill the bearing with grease as it could lead to overheating and reduced bearing life. It is generally better to use less lubrication more frequently than more lubricant less often. If the unit will not be operated for an extended period of time extra lubricant should be added to prevent corrosion. If the unit has not been operated for an extended period of time fresh lubricant should be added prior to start-up. If the unit becomes too hot during operation from over-lubrication remove the grease fitting and operate the unit for approximately thirty minutes to allow excess grease to purge. ppropriate lubrication intervals can be determined by referring to Table ; however experience should largely determine the actual lubrication regimen for a particular application. Consult with an FYH representative for assistance. If a suitable Calcium ulfonate lubricant is not available for re-lubrication then the following compatible lubricants may also be used: arium Complex, Calcium tearate, Lithium Complex, Polyurea (hear table) The use of any other type of lubricant should be avoided to prevent compatibility issues with the Calcium ulfonate grease that is originally supplied. To find the proper lubrication interval in Table obtain the relevant percentage of max allowable RPM by referring to Table. Example: X4 with positive contact seals has a max RPM rating of. If the application has an RPM of then the percentage of max RPM is % ( =.). The amount of grease for replenishment can be found in Table.
