5 MOUNTE BEARING ENGINEERING SECTION Ball Bearing Size Selection A bearing should be selected with a load rating the same as or greater than the actual load. Where overloads, shock, vibration or thrust loads are encountered, use the largest equivalent load to select the bearing, as shown in the following three paragraphs.. For applications involving frequent overloads, the overload value should be used as the equivalent load.. For applications involving shock loads or vibration, add up to 0% of the actual load to find the equivalent load.. If thrust loads exceed 0% of the radial load, add the thrust load to 0% of the radial load to determine the equivalent load. When an 0 life of over 0,000 hours is required, multiply the actual or equivalent load by the following factors:.0 for 40,000 hours 0 life.6 for 60,000 hours 0 life. for 80,000 hours 0 life.0 for 00,000 hours 0 life Find this new value in the table opposite 0,000 hours 0 life in order to select a bearing. The 0 life as given in the table is defined as the number of hours that 0% of a group of bearings will operate before the first evidence of fatigue develops. Average life is approximately five times 0 life. Because of the high load permitted at low speeds, shaft strength and housing clamping bolt strength should be checked for low speed operation. Heavy thrust applications require a shouldered shaft back-up against the face of the inner ring or an added thrust collar. Mounted bearing units have the advantage of providing proper load support and reducing design and assembly time. Pre-mounted bearing units offer convenience as well as economy and it is not necessary to spend valuable time selecting bearing housings, seals and different methods of securing the bearings to the shafts. Selection information usually necessary is shaft size, radial and thrust loads, speed and physical mounting limitations and operating environment. The simplest, most economical mounting is set-screw locking through the inner race which securely locates the two members. The extended inner race provides maximum shaft contact along with good bearing stability. For some installations, standard commercial shafts are successful with a slip fit in the inner race bore, although some instances, press fitting of the shaft to the inner race is required. The amount of inner race bore to shaft O.. clearance that can be tolerated depends upon application and operating conditions. For instance, if dynamic balance is important, a close fitting shaft to inner race bore is very desirable. Severe vibration could be experienced when using undersize shafts of varying degrees resulting in the undersize shaft becoming eccentric in the bore of the inner race, regardless of the type of locking method. Three types of shafting are normally used in ball bearing pillow block applications. For example, it is very common to utilize commercial grade mild steel shafting. If closer tolerance shafting is required, then either turned, ground and polished or cold drawn, ground and polished shafting is used. If more precise shafting is required, it can be selected to, or purchased, with a diameter tolerance and it is usually to the nominal diameter with a negative tolerance. If the dynamic balance is important, slightly oversize shafting should be used to provide a snug fit with the bore of the inner race. In other words, it should be a line to line fit to an interference fit rather than a line to line to a non-interference fit. Special mounted bearings In addition to standard bearings cataloged, bearings are available with special surface finishes, special sealing arrangements and specialized housing or bearing insert configurations. Special surface finishes A black oxide surface finish treatment can be applied to ball bearing inserts to meet special application requirements. The black oxide finish is applied for corrosion resistance, and provides excellent protection for the majority of application conditions. Also, it is far less costly than a plated bearing or a bearing made entirely of stainless steel. Nickel plated pillow blocks PATE A variety of standard mounted units have been supplied with nickel-plated castings for food processing or food packaging applications. Bearing inserts with black oxide finishes are normally supplied with nickel-plated casting unless otherwise specified. Stainless steel set screws are considered optional and would not be included unless specified. Applications where nickel-plated mountings are being used include: vegetable peeling, fruit and vegetable forming and stacking equipment, shrimp peelers and many conveyor applications where the bearings are exposed to food acids, as well as daily detergent and steam washdowns. Nickel plated housing have excellent corrosion resistance (approaching that of cadmium plating) and wearability similar to chrome plating. These bearings are prelubricated with an odorless, tasteless grease that meets Section. subpart F ubricants with Incidental Food Contact of the food additive regulation of the Good and rug Administration. The lubricant has capabilities to adequately lubricate antifriction bearings under wet or dry conditions and in normal ambient temperatures to an operating temperature of + F. Nickel plated units are available in C, FC, FC4, TC configurations in /" to /6" bore sizes. Catalog numbers of nickel plated units are formed by adding the prefix letter N ahead of the standard bearing number. Example C- standard pillow block becomes NC- with nickel plating and corrosion resistant bearing insert. 4

6 MOUNTE BEARING ENGINEERING SECTION (Cont.) Specialized housings or bearing inserts Specialized housing or bearing insert configurations are frequently supplied to suit application needs. A few examples are: Non-standard based to shaft centerline height, Relocation of lube fitting, Non-standard mounting bolt hole location or shape, Triangular flange castings, ust closures, one side of housing, ouble extended inner ring bearing inserts with set screws on each side, Square and hex bore bearing inserts, and Triple contact lip sealing, commonly called for in farm equipment applications. Special housing designs may be proprietary and not available to others. However, in some cases tooling is standard and existing special designs can be made available. Special paint colors or types are also available, and Some customers have made use of a special marking option available with MB bearings. The units can be marked with customer identification (name) and/or number. This personalizes the unit and the equipment in which it is used. Instructions for installation and lubrication of mounted ball bearing units CAUTION Failure to comply with proper installation, lubrication and maintenance procedures could result in catastrophic bearing failure. If operating in an explosive environment or in or around combustible materials, such catastrophic failure could lead to property damage and personal injury. Important Notice The performance of any mounted unit is dependent upon proper installation, lubrication and maintenance. Premature failure may result if recommended instructions are not followed. Installation The shaft must be clean and free of nicks and burrs. If mounted on used shafting, the bearing must be located on a smooth, unworn section. a. A ground shaft must be used to obtain a snug fit, except where the unit is used for heavy loads, high speeds or where dynamic balance is critical, in which case a light press fit is required. The following shaft diameters and tolerance must be used to obtain a snug fit: Shaft iameters, Inches Tolerances, Inches, From Nominal / to to.000 to / to.000 Heavy loads are greater than % of the ynamic Rating (BR) of the bearing used in the mounted unit. The oad Ratings are shown on page 0 or page 40. High speeds are those defined as being in excess of,00 feet per minute. b. To obtain a light press fit, a line-to-line fit between the bearing bore and the shaft diameter must be maintained. Any fit tighter than line-to-line can cause premature bearing failure. Thus, selective fitting of bearing bores and shaft diameters is required to maintain proper light press fit for heavy loads, high speeds or when dynamic balance is critical. c. For moderate thrust loads, shock loads, vibration conditions or higher speeds, the shaft should be spot drilled to provide additional holding. Heavy thrust load applications require a shouldered shaft back-up against the inner ring face, or an added thrust collar.. Even very small raised edges and burrs on the mounting surfaces can lead to overstressing and fracture of the housing. Therefore, the support member surface to which the housing will be mounted, and the housing mounting surface, must be clean and free of burrs and nicks that have raised edges, so that a smooth, flat mounting surface is present. Careful handling of mounted units is required to avoid damage to the mounting surface.. Slide the unit on the shaft by applying light pressure against the face of the inner ring. O NOT HAMMER THE ENS OF THE INNER RING OR ANY PART OF THE HOUSING. 4. Bolt the housed units securely to the support members.. Tighten the set screws of one bearing locking device to the recommended torque values given in Chart, below. a. Bearings with the concentric setscrew locking device have no collar-the set screws in the inner race extension tighten against the shaft. b. Bearings with the CENTRIK-OK locking device have a collar. The set screws in the collar are started into countersunk holes in the inner race extension. These set screws must be tightened to the Chart recommended torque values into these countersunk holes to obtain satisfactory and efficient locking to the shaft. 6. Check the shaft for freedom of rotation. If possible, run the bearings a short time under the load.. Tighten all bearing set screws to the Chart recommended torque values. Set Screw Size ubrication CHART RECOMMENE SET SCREW TORQUE Socket Size # 0 / /4 / 4 8 Pound-Inches Pound-Feet Min Max Min Max All standard MB ball bearing mounted units are prelubricated with grease and must be periodically relubricated to obtain full bearing fatigue life. This is even more important when these units are used in a dusty or moist environment. The required lubrication cycle will be dependent upon the operating conditions, speed, temperature, dust, moisture and other environmental conditions. The following lubrication guide must be followed to prevent catastrophic bearing failures: Conditions ust Moisture UBRICATION GUIE Minimum Relubrication Interval aily to twice weekly Twice daily to weekly } See par. b on page 6

7 MOUNTE BEARING ENGINEERING SECTION (Cont.). Grease should be added slowly while the shaft is rotating, until a slight bead of grease forms at the seals. This indicates the correct amount of grease has been added. A slight grease leakage at the seals is beneficial as it assures lubrication of the seal contacts, purging of old grease from the bearing and provides protection in the form of a grease dam against contamination. CAUTION: Proper care must be exercised during relubrication to avoid any rotating parts that would cause personal injury.. MB mounted ball bearing units are prelubricated with lithium base grease for normal operating conditions and a temperature range of 0 F to + F. These units must be relubricated with a lithium base grease, or a grease recommended by a reputable grease manufacturer as being suitable for ball bearings and compatible with lithium base greases. a. Relubrication will generally cause a slight rise in bearing operating temperature until the bearing has stabilized with the proper amount of lubricant. Under normal conditions, this slight rise in operating temperature should not exceed 0 F. This will usually take place within a period of 0 to 0 minutes following the relubrication. b. Some environmental operating conditions, such as an unusual amount of dust, operation in dirt or in moist environments, will require more frequent relubrication with as much grease as possible while maintaining a normal bearing operating temperature range of ambient to approximately 0 F. Relubrication should be as often as necessary to maintain a slight grease purge at the seals. c. In the event bearings are to be stored in a wet, dusty or corrosive environment, extra protection must be provided by first adding grease and rotating the bearing until the grease is seen at the seals. In addition, fresh grease must be added before operation, when stored under such adverse conditions.. Special optional sealing arrangements are available for unusual adverse operating conditions. Normally, a special grease prepack is required in conjunction with special sealing arrangements. The Rexnord Bearing Products Engineering epartment should be consulted for special application conditions and/or abnormal or severe environmental conditions. IMPORTANT NOTICE Periodic relubrication, at a frequency that will be determined by application conditions, is absolutely necessary to avoid catastrophic bearing failure. In addition, periodic inspection must be made to assure continued satisfactory bearing operation. uring such periodic inspection, bearing operating temperatures should be checked. If operating temperatures are found to be rising, the reason for this should be determined. It may be that replacement of the mounted bearing is required. Temperature sensitive crayons and temperature sensitive labels can be used for determining bearing temperature. Marking the housing with temperature sensitive crayon or applying a temperature sensitive label to the housing will indicate if the bearing operating temperature has exceeded a prescribed level. At any time the bearing operating temperature has exceeded a prescribed level, or any time the bearing operating temperature exceeds 0 F, the reason should be be determined. Replacement of the mounted unit may be necessary. Special procedures and safety codes must be followed. This may require the use of protective guards or other devices. Temperature sensitive crayons or labels, protective guards and other safety devices are not provided by MB nor is their use or lack of use the responsibility of Rexnord Bearing Products. Bearing Insert Replacement. The MB bearing insert has mounted in its spherical outside surface and anti-rotation pin, unless the bearing package is marked W/OP. To be effective, this antirotation pin must engage one of the loading slots in the cast housing.. In addition to the anti-rotation pin, MB housings and bearing inserts are fitted together to provide controlled limits on torque required to align the insert in the spherical seat of the housing. Failure to observe the prescribed alignment torque values can lead to premature bearing failure. Those alignment torque values can be obtained from the Rexnord Bearing Products Engineering epartment. CAUTION: The replacement of MB inserts into housing of other manufacturers can lead to premature bearing failure. The lubrication fittings in other housing designs may not line up with the lubrication groove and hole in the outer ring of the MB bearing insert. If that occurs, the bearing will not receive lubricant at relubrication and early, and possible catastrophic, failure can occur:. Installation of an MB bearing insert into an MB cast housing is initiated by installing the bearing into the housing insertion slots with the bearing turned 0 from its normal position, and with the anti-rotation pin located in one of the insertion slots. Care must be exercised to avoid shearing the rotation pin when the bearing is gimbaled to its final position, and the bearing must be gimbaled so that the anti-rotation pin (located closer to one face of the bearing out race) is in position toward the insertion slot face of the casting. Further, the bearing insert should be installed so that the lubrication hole in the outer ring outside surface is approximately in line with the lubrication fitting in he housing. The lubrication groove in the outer ring outside source must be under the housing lubrication fitting. 4. After bearing insert assembly in housing, the aligning torque must be checked with a torque wrench to verify satisfactory aligning torque. Failure to do so and/or shearing the anti-rotation pin can lead to spinning of the bearing outer race in the housing with resultant housing wear and premature unit failure. 6

9 KROWN REGA CENTRIK-OK MOUNTE Ball Bearings (cont.) Flinger Standard N Seal Optional E Seal The KROWN REGA bearing design reduces the three most common causes of bearing failure seal failure that permits entrance of contaminants or loss of lubricant; insufficient housing strength; and loosening of bearings on rotating shafts. Other features include large diameter balls for high load capacities, nylon retainers for quiet operations, conveniently located lube fittings and superior anti-rotation pin arrangement. Molded ip Seal-Flinger System The sealing system provides four-way sealing action to effectively keep dirt out and lubricant in. It is combined in KROWN REGA bearings with steel flingers that throw excessive contaminants away from the bearings and protect the seals from damage by abrasives and impact. Together, the superior seals and added flingers add significantly to bearing life. Rugged one-piece cast iron housings These bearings have heavier cast iron housing than previous designs. The KROWN REGA foot-mounted pillow blocks and flange mounts are built to withstand heavy loading, shock and external vibration. Finishes are highly resistant to corrosion and abrasion. CENTRIK-OK shaft locking device Bearing-to-shaft locking is accomplished with the patented CENTRIK-OK shaft locking device. This method of locking provides excellent holding power versus competitive shaft locking devices. Its clamping action also centers the shaft in the bearing to avoid vibration and noise. It also eliminates shaft damage because set screws do not contact the shaft making bearing removal easier. Spherically-seated bearing insert with antirotation pin The spherical fit between the outer race O.. and I.. of the block is precisely controlled for easy shaft alignment. An antirotation pin is permanently installed in the bearing insert O.. It engages one of the housing insertion slots, preventing outer race creep and war of housing. There is no danger of losing a separable pin during field replacement of bearings and no danger of preloading the bearing as is possible in other designs where a lube fitting is tightened against a locking pin. oading Slot Conveniently-located ube Fitting Anti-rotation pin 8

10 KROWN REGA precision mounted ball bearings with patented CENTRIK-OK shaft locking device. The CENTRIK-OK shaft locking device (Pat. No. 4,40,84) assures precise centering of MB KROWN REGA ball bearing pillow blocks and flange-mounted units on rotating shafts to avoid vibration and noise. What s more, the inherent holding power of this unique design can be far superior to other equivalent competitive bearings. An important feature of the CENTRIK-OK shaft locking device is that the locking collar is pre-assembled onto the bearing inner race, avoiding the problem of loose, lost or misplaced locking collars. Another feature is that the set screws do not come in contact with the shaft and therefore, do not mark the shaft or leave heavy burrs that make bearing removal difficult. Most mounted bearing locking devices move the inner race eccentrically on the shaft during locking. This eccentric positioning of the inner race can cause vibration, loosening of locking devices and loss of bearing performance. One of the drawback of current locking devices that do maintain concentricity has been their lack of shaft-holding power. The CENTRIK-OK shaft locking device overcomes these shaft-holding limitations and still provides the advantages of true concentricity. The inner race is slotted in four places and a continuous cylindrical locking collar is applied over the inner race slots. Two set screws, located 4 apart, contact the inner race on each side of one of the slots. The two set screws exert force on two of the four inner race segments and the resulting reaction through the collar pulls the remaining two segments against the shaft concentrically.

38 MOUNTE BA BEARINGS designed for long life and precision performance. MB bearings provide design and performance features developed by decades of experience in supplying precision ball bearing inserts for other major mounted bearing manufacturers and complete mounted units to machinery and equipment manufacturers. They are priced competitively to bearings of comparable construction. In addition to sound basic design and construction, special features minimize the three most common causes of premature bearing failure loosening of bearings on rotating shafts, entrance of contaminants or loss of lubricant due to seal failure and insufficient housing strength. Standard duty and medium duty foot-mounted pillow blocks, flange units, take-up blocks and hanger bearings cataloged in the following pages are available from stock. For other sizes, mountings or special requirements to fit your applications, please consult the Rexnord Bearing Products.

39 Flinger Standard N Seal Optional E Seal Concentric setscrew shaft locking device The MB method of fastening the bearing inner race to the shaft provides substantial improvement in holding power compared to eccentric locking collars and even greater improvement over 0 set screw positioning, over-collars and other types of locking arrangement. Combination seal-flinger system Optimum protection from loss of lubricant and entrance of dirt and contaminants is achieved with positive lip-type contact seals. The resulting longer seal life extends bearing life significantly. Rugged, one-piece cast iron housing Housings are designed to withstand bearing load ratings, external vibration and shock. Foot mounted pillow block bolt holes are elongated for easy installation and adjustment. Spherically-seated bearing insert with antirotation device The spherical fit between the outer race O.. and I.. of the block is precisely controlled for easy shaft alignment. The anti-rotation device is permanently installed in the bearing insert O.. It engages one of the housing insertion slots, preventing outer race creep and wear of housing. There is no danger of losing a separable pin during field replacement of bearings and no danger of preloading the bearing as is possible in other designs where a lube fitting is tightened against a locking pin. oading Slot Conveniently-located ube Fitting Anti-rotation pin 8

40 PRECISION MOUNTE BA BEARINGS with shafting locking device MB concentric setscrew precision mounted ball bearings feature a concentric setscrew shaft locking device, resulting in a great improvement in the holding power (locking efficiency). Field experience shows substantial improvement in holding power when compared to eccentric locking collars and even greater improvement in locking efficiency when compared to 0 set screw positioning and other types of locking arrangements. The locking set screws are located at a 0 angular relationship, rather than the traditional 0. A force diagram showing the 0 comparison of the locking characteristics of the old 0 set screw spacing and the 0 shaft locking device, superimposed on an end view of the inner ring, provides a more graphic illustration of the reason for the locking improvement. The force diagrams are arranged with an assumed,000 pound normal force between each of the set screws and the shaft. If each of these forces is resolved into its horizontal and vertical components, as shown in the view, it is seen that the effectiveness of the two horizontal components is lost because they cancel. The two vertical components are additive, resulting in a force between the shaft and the inner ring bore at the side opposite the bisector of the angle between the two set screws, equal to the sum of the two vertical components. When the setscrew angle is at 0, the horizontal and vertical load vectors are equalized. This optimization provides sufficient holding power to the shaft seat while controlling ring distortion. The results are a bearing that operated smoothly while achieving prolong shaft seat mounting tightness. The positioning of the set screws has the further advantage of simplifying the set screw locking procedure. Rather than having to rotate the shaft (and other heavy components attached to it) through a large angle to alternatively tighten the set screws, the 0 locking device requires little or no movement of the shaft, to insure proper tightening. This is especially valuable where surrounding installation components limit maneuverability. In this type of application it can save installation time as well as assuring proper assembly. 000 Normal 0 Setscrew Spacing 000 Normal Vertical 4 00 Vertical 866 Horizontal 0 Vertical 0 Horizontal 0 Setscrew Spacing 44 Vertical

The conductive rubber adapter is intended to alleviate electrical static charge build-up often encountered in some air moving equipment applications. The rubber supported bearing insert provides vibration dampening, which aids considerably in reducing noise level. These units are intended primarily for any light duty applications, such as fans, or blowers and are particularly well suited for heating, air conditioning and ventilating equipment where quiet installations are desireable. This would include any applications where any vibration or noise amplified by connecting duct work would be considered very objectionable.

67 ER TYPE BA BEARING INSERTS ER type bearing inserts are commonly used in mounted bearing assemblies. The bearings have basic standard metric ball bearing dimensions with the exception of widths and the inch size bore of the inner ring. Because of the metric ball bearing basis of design and sizing, the ball complement (the number and size) for a given size bearing is comparable with other manufacturers. The ER type insert is designed for set screw locking to the shaft, with the bearing mounted in the customers housing. It incorporates standard seals and comes with a O.. mounted snap ring for axial location, eliminating housing counterboring. ER series bearings are intended for rigid mounting, as the bearings have a cylindrical O.. and not the spherical O.. of standard insert bearings.

When bearings are subjected to very heavy or vibratory loads, it may be necessary to employ shaft and housing fits tighter than standard. The same applies if shafts or housings of soft metal or those not having smoothly ground bearing seats (i.e., the smoothness ordinarily associated with ground or reamed bores) are used. The bearing bore is made so that a sliding fit is produced on the shaft. For best results, a ground shaft should be used to obtain a snug fit. A light press fit is advisable for heavy loads or where dynamic balance is important. The following tolerances are recommended for nominal shaft diamters: Shaft /"-/6" plus.0000 to minus.000 iameter{ "-/" plus.0000 to minus.000 These recommended shaft tolerances are for bearings applied under the load and speed conditions listed in the load rating tables. Consult Rexnord Bearing Products for extreme or special operating conditions. Furthermore, if speeds are abnormally high, it may be necessary to maintain shaft and housing fits other than those shown in tables. Consult Rexnord Bearing Products engineering department for recommendation on any abnormal conditions. 66

69 STAMPE STEE PIOW BOCKS AN FANGETTES Stamped steel pillow blocks, consisting of a two piece stamped steel housing with a spherical bearing seat to match the spherical radius ground on the bearing O.. for light duty applications, provide the advantages of a ball bearing construction in an economical low cost unit. The base-to-shaft centerline height and bolt hole space of these units make them readily interchangeable with many standard mounting on the market. All the stamped steel mounted units are easily adaptable to a variety of applications. The units are often used very successfully in application where the unit is selected for a given shaft size, for economic reasons, rather than for load rating. However, it should also be stressed that consideration should be given to the load rating and the unit should not be selected merely for the shaft size. The load rating is based on the strength of the specific stamped steel mounting rather than the bearing insert. It is important that the inner ring set screws be tightened securely against the shaft before the stamped housing is attached (fastened) to the mounting surface. The self aligning feature of the stamping clamps the bearing O.. when the mounting bolts are tightened and makes any additional alignment of the bearing insert within the mounting impractical. Stamped steel flanges or flangettes consist of two interchangeable pressed steel flanges with spherical inside surfaces to form a mating contour to accomodate the spherical O.. of the bearing insert. These are usually made in two, three and four bolt designs with standard mounting dimensions, or on a special basis to fit specific applications. They are low cost units for light duty and moderate speed applications. U K BOTS-F H A B Min B Max C E PS SERIES STAMPE STEE PIOW BOCKS Pillow B Block Number Size A mm I nches M in.
