0 Technical Introduction Bearing Structure General Construction Most bearings consist of rings (inner and outer ring) with raceways, Rolling elements (balls or rollers) and a rolling element retainer (cage). The retainer seperates the rolling elements within specific distance, holds them in place and allows them to rotate freely within the raceways of the bearings. The adjoining figures show the relative positioning of the rings, rolling elements and the retainers for the various types of bearings. Selection of Bearings Outline of Bearing Selection Currently bearing design has become increasingly complex and diverse. A large part of the performance relies on the correct selection of the bearing. To select the most suitable bearing it is necessary to conduct a comprehensive study on bearings and the equipment in which the bearing will be installed, including operating conditions, performance required, specifications of other components to be installed alongwith the bearings and other criteria. Below is a quick guide which can be used for selection of the bearing. Characteristics of Bearings Most bearings have very low friction coeffecients. In general all bearings can carry radial and axial loads in varying capacities based on their type and construction. Ball bearings in general are used in applications that have high speed, high precision, low torque and lower vibration since they have lower frictional coefficients and lower face runout during rotation. Comparatively roller bearings are used in applications that have lower speeds, high loads and are subjected to torque and vibration forces. Selection of Bearing Arrangement Bearings are further installed based on the arrangment of the bearing on the shaft and on the properties and operation of the shaft. Depending on availability of fixed and free side of the shaft different bearings can be used for the shaft. 6 7

Static loads and Dynamic loads. Static loads refer to loads applied to the bearing in stationary state (or nearly stationary state i.e. when n<0 min. ). Dynamic loads are subjected to bearings when there is relative movement between the rings of the bearing. The theoretical rating life (length of time for which the bearing can operate without mechanical failure) calculation is standardized internationally as per the ISO 28 standard. This standard is based on Lundberg and Palmgren s theory of fatigue. Industry Wise Required Rating Life If no information is available then values from below general guide can be used to estimate the rating life required for different industries. Basic Rating Life The basic rating life calculated in accordance to ISO 28 is as below: Industry Type Required Rating Life L = (Cr / P) P where L = (Unit: Million Revolutions)Basic rating life in millions of revolutions reached or exceeded by a sufficiently large number of identical bearings before first indications of material fatigue appear Cr = (Unit: Newton N) Basic dynamic load rating. P = Equivalent Bearing load p= Life exponent. Ball bearings; p = 3 The rating life is also expressed in operating hours and the formula for that is: L = 6667. L n where Operating Hours n = (revolutions per minrpm) operating speed. Adjusted Rating life The adjusted rating life in accordance to ISO 28 can be calculated if other influencing factors in addition to the speed and load are known. These factors include: special material properties or If reliability over 90% is required. Correction of basic dynamic load rating for high temperature use In high temperature operation bearing material hardness deteriorates, as material compositions are altered. As a result, the dynamic load rating is reduced. To account for this reduction the basic dynamic load rating is multiplied by the temperature coeffecients shown below: Bearing Temp 50 75 0 0 Temperature Coeffecient 0.62 0.53 0.44 3 Lna = a. a2. a3. L where L = Basic rating life a = life adjustment factor for a reliability other than 90% (as shown below) a2 = life adjustment factor for special material properties (standard Chromium steel: a2 = ) a3 = life adjustment factor for special operating conditions in particular related to lubrication 0

Notes 0 Technical Introduction Date:... Bearing Tolerances Tolerances and Tolerance Classes Bearing tolerances and values for boundary dimensions are standardized and specified. This is done by classifying the bearings into 6 classes: 0, 6X, 6, 5, 4 & 2. Class 0 bearings are used for general applications and class 5 and above are used for high speed & high accuracy applications. The tolerances are based on ISO standards. Tolerance limits have been set for boundary dimension accuracy and for running accuracy. These are subdivided as follows: Running Accuracy. Radial and Axial runout of inner and outer rings 2. Side face runout in relation to inner ring bore 3. Inclination of outside cylindrical surface 4. Thrust Bearings raceway thickness Boundary dimensions. Inner ring bore diameter 2. Outer ring outside diameter 3. Inner ring Width 4. Outer ring Width 5. Outside diameter of rollers 6. Chamfer dimensions 7. Width variation 8. Tapered Bore 4 5

In the case of some bearing types radial and axial clearances depend on each other. There is a distinction made between the clearance of the bearing prior to mounting and the clearance of the mounted bearing at operating temperature(operating clearance). The operating clearance should be as small as possible for the shaft to be guided perfectly. The clearance of the nonmounted bearing is reduced during mounting due to tight fits of the bearing rings. As a rule, it therefore has to be larger than the operating clearance. The radial clearance is also reduced during operation when the inner ring becomes warmer than the outer ring, which is usually the case. DIN 6 specifies standard values for the radial clearance of bearings. The normal clearance of rolling bearings. The normal clearance (clearance group CN) is calculated in such a way that the bearing has unappropriate operating clearance under common mounting and operating conditions. Normal fits are: Shaft Housing Ball Bearing j5 k5 H7 J7 Roller Bearing k5...m5 H7 M7 Mounting and service conditions which deviate, such as tight fits for both bearing rings or temperature difference > 0K, make more radial clearance group necessary. The suitable clearance group is calculated. Suffixes for the clearance groups according to DIN 6: C2 Radial clearance smaller than normal (CN) C3 Radial clearance larger than normal(cn) C4 Radial clearance larger than C3 Reduction of the radial clearances by means of temperature differences: The reduction of the radial clearances ^ grt by means of temperature differences ^t (K) for non adjusted bearings is approximately: ^grt = ^ t. alpha.(d+d)/2 27

0 Technical Introduction Where Alpha = 0.0000K Linear thermal expansion coefficient of the steel dbearing bore D Bearing outside diameter A greater change in radial clearance can be expected when the bearing position is exposed to the input or dissipation of heat. A smaller radial clearance results from heat input through the shaft or heat dissipation through the housing. A larger radial clearance results from heat input through the housing or heat dissipation through the shaft. Rapid runup of the bearings to operating speed results in greater differences in temperature between the bearing rings than is the case in a steady state. Either the bearings should be run up slowly or a larger radial clearance than theoretically necessary for the bearing when under operating temperatures should be selected in order to prevent detrimental preload and bearing deformation. Reduction and radial clearance by means of tight fits: The expansion of the inner ring raceway and the constriction of the outer ring raceway can be assumed to be approximately 80% and 70% of the interference respectively.

This kind of load is known as preload and is very often applied to tapered roller and angular contact ball bearings. Preload Purpose The purpose of the preload is as follows: a) To Improve the running accuracy b) To Improve gear engagement accuracy by increasing rigidity c) To reduce smearing by reducing sliding in irregular rotation d) To minimize abnormal noise due to vibration e) To keep rolling elements in right position relative to raceway. Preload Methods Application of preload is achieved in one of the following ways: ) Position Preloading 2) Constant Pressure Preloading Method of Preloading 32 33

0 Technical Introduction Purpose is one of the most important factors determining bearing performance. The suitability of the lubricant and lubrication method have a strong influence on bearing life. has the following function: a) To lubricate each part of the bearing and reduce friction and wear b) To carry away heat generated inside bearing due to friction. c) To cover rolling contact surface with the proper oil film. d) To Prevent corrosion and contamination Type of Bearing lubrication is classified broadly into : a) Grease b) Oil The main differences between them are as follows: Item Grease Oil Sealing Easy Slightly complicated and special care required Lubricating ability Good Excellent Rotation speed Low/medium Applicable at high speed Replacement of lubricant Slightly troublesome Easy Life of lubricant Relatively short Long Cooling effect No cooling effect Good (with circulation) Filtration of dirt Difficult Easy DPI DGMT 3 Grease For best results use DPI DGMT 3 Grease. This is specially formulated in the EU with wide use all over the world with our customers and bearings. Material Bearing materials include steel for bearing rings and rolling elements, as well as steel sheet,steel, copper alloy and synthetic resins for cages. These bearing materials should possess the following characteristics : ) High elasticity, durable under high partial contact stress. 2) High strength against rolling contact fatigue due to large repetitive contact load. 3) Strong hardness 4) High abrasion resistance 5) High toughness against impact load 6) Excellent dimensional stability ) High Carbon Chromium Bearing Steel Bearing ring Rolling elements Cages Bearing ring Rolling elements High carbon chromium bearing steel specified in Indian/Chinese Standard is used as a general material in bearing (inner rings, outer rings) and rolling elements (balls, rollers). Among these steel types, SUJ 2 is generally used. SUJ 3, which contains additional Mn and Si, possesses high hardenability and is commonly used for thick section bearings. SUJ 5 has increased hardenability, because it was developed by adding Mo to SUJ 3 for small and medium sized bearings, SUJ 2 and SUJ 3 are used, and for large size and extralarge size bearings with thick sections, SUJ 5 is widely used. Generally, these materials are processed into the specified shape and then undergo hardening and annealing treatment until they attain a hardness of 57 to 64 HRC. 2) Case Carburizing Bearing Steel (Case Hardened Steel) When a bearing recieves heavy impact loads, the surface of the bearing should be hard and the inside soft. Such materials should posses a proper amount of carbon, dense structure, and carburizing case depth on their surface, while having proper hardness and fine structure internally. For this purpose, chromium steel and nickelchromium molybdenum steel are used as materials. These materials also undergo vaccum degassing in order to reduce nonmetallic inclusions and oxygen content which leads to higher reliability. 34

02 Deep Groove Ball Bearing Deep groove ball bearing are the most popular and support radial and certain degree of axial load in both direction simultaneosly. The following types of ball bearings are available:.shielded / Sealed type This simplifies the sealing. Greasing is not necessary because bearings are prelubricated. The various types of seals are as follows: a) ZZ (noncontact) Shield: This is good in applications that require small frictional torques and high speed with good resistance of dirt. These have very limited resistance of water. Deep Groove Ball Bearing b) 2RS/LLU (contact type) seal: This is good in applications that require large frictional torques. They have limitations in high speed applications due to the contact of seal. The grease sealing and direct and water resistance is very good. 2.With locating snap ring These can be fit into housings easily as the locating snap ring facilitates acial positioning. 3.Extrasmall ball bearings & iature ball bearings The open type is widely used. The standard cages used are pressed steel cages. Additionally copper alloy machined cages are also available. DPI ball bearings are the most popular products. These are well known for there quality and performance. Our standard quality has made the ball bearing series very popular in most of the markets.

03 Angular Contact Ball Bearing Angular contact ball bearings are ideal for applications which require accuracy and speed. These kinds of bearings are required to carry a combined load. The following different types of angular contact bearings are available:.shield / Sealed type. The standard contact angles are 5 degrees (C), degrees (A) and degrees (B). Smaller contact angles are suitable for higher speed applications. large contact angles provide better axial resistance. These bearings are also available as matched pair bearings where they are matched as follows: Angular Contact Ball Bearing a) BacttoBack (DB): These are arranged so that the distance between the load centers is long and hence this arrangement will sustain larger moment loads. b) FacetoFace (DF): These are arranged so that the distance between the load centers is short and hence ability to carry moment loads is smaller. c) Tandem Arrangement: This arrangement is useful for applications that require high axial load. 2.Double Row Contact Bearings: These consist of two single row angular contact ball bearings matched backtoback with integrated inner and outer rings. 3.Four Point Contact Bearings: These have a contact angle of degrees. The inner ring is divided into 2 pieces. These are very speacialized bearings. The standard cages used are pressed steel cages. Additionally copper alloy machined cages are also available. For details on boundary dimensions and specifications please refer to the tables overleaf 67

03 Angular Contact Ball Bearing Radial Trust Ball bearing Angular contact ball bearings can hear radial loading and axial load simultaneously, and single row angular contact ball bearings can only bear single direction axial load, therefore, they are often used in pairs, When used in pairs, the paired angular contact ball bearings with preset gap are most convenient. The contact angles between steel balls and the inner race/outer race are 5, and. The larger its contact angle is the higher axial load it can bear. Smaller contact angle is good for high speed rotation. Generally, high precision and high speed bearings often adopt the contact angle of 5. Table the structures and features of paired duplex angular contact ball bearing Standard Structures Features Back to back paired duplex E.g: 79 CDB Can bear radial loading and axial load from two from directions. The application point distance a0 is large, are applicable where the torque load is large.. Single Row angular contact bearing The type of bearings has contact angle, so they are suited to bear single direction axial load, or combined load. Structurally, they generate axial thrust load after bearing radial loading, so two bearings shall be ised in pairs, or more that two back to back duplexes. The rigidity od single row angular contact ball bearings can be improved through pretension. Therefore, they are applied to the principal axes of high rotation precision machine tools. etc. Back to back paired duplex E.g: 79 BDF Parallel paired duplex E.g: 79 CDT Can bear radial loading and axial load from two from directions. Compared with back to back paired duplex, the application point distance is smaller, so the torque load capacity is no good. Can bear radial loading and axial load from one directions. Bearing axial load with two bearings, so used where the single direction load is large. The contact angles of standard products include 5 (code C). (code AC) and (code AC). The retainers of bearings with 5 and contact angles are often made of bakelite. The materials of the retainers of contact angle bearings include copper, nylon, steel sheet etc. In addition, where the retainer structures of the same bearing specifications are different and the number of ball varies, the load ratings are also different from the values in dimension table. For 5 (code C) and code (AC) angular contact ball bearings, high precision above P4 grade can be achieved. These products are especially suited for the principal axes of high speed and high machine tools and spinning frames. 2. Paired duplex angular contact ball bearing The structures and features of paired duplex angular contact ball bearings are shown in Table. Note: The dimension table does not provide the value of the application point a0. Please contact technical center of DPI if required. 3. Double row angular contact ball bearing The inner and outer races of the back to back duplex bearings are combined into one structure, which can bear tow directional axial loads, and the torque load capacity is large. They can be used as restrained end bearings. Pressed retainers or nylon retainers are often used. 4. Four point contact ball bearing Inner race is divided into two, and one bearing bears axial from two directions. Contact angle is, axial load capacity is high, suited to bear net axial load, or resultant load whose axial load is high. Copper alloy lathe retainers are often ised. 68 69

04 Self Aligning Ball Bearing Self Aligning ball bearings have spherical outer raceway. The centre of this raceway coincides the centre of the bearing itself. Due to this specific design the rolling elements rotate and align themselves in the event they are misaligned. These are very useful in applications where there is displacement of the centers around the shaft and housing rotate and deflection are likely to occur. The standard cage used are staggered type pressed steel cages an snap type pressed steel cages. Additionally Copper alloy machined cages are also available. Self Aligning Ball Bearing For details on boundary dimensions and specifications please refer to the tables overleaf. 83

04 Self Aligning Ball Bearing Self aligning ball bearing The outer ring raceway of self aligning roller bearing is a spherical surface, its center of curvature corresponds with the bearing center. Therefore, the inner race, outer race, ball and retainer can inclines at a certain degree, and can be rotate freely around the bearing center. Its automatic self aligning ability can correct the desaxe caused by improper processing and installation automatically. It is applicable where axle and case centering is difficult and axle is easy to be crooked. Self aligning roller bearings is mostly used to bear radial load. While bearing radial load, it can also bear a small amount of axial load, but not suitable to bear net axial load. Thanks to the self aligning ability of this bearing, it is suited where the speed is low and self aligning is required. Where the loading capacity of the self aligning ball bearing is not enough, the self aligning roller bearing with self aligning ability shall be used. Application scope of self aligning ball bearing: driving shafts of woodworking machinery and textile machinery. Self aligning ball bearings bore is column inner bore or taper inner bore. The tapering of taper inner bore is :2 (suffix is K). DPI can provide self aligning ball bearings whose bore surfaces have cylindrical inner bores or taper inner bores. DPI can provide seal self aligning ball bearings with lengthened inner races can facilities the installation and dismounting. Please consult the technical center of DPI if required,. Structural form. Conventional type (Fig. ): Self aligning ball bearing whose internal bore surface is cylindrical: 2. Taper bore type (Fig. 2): Self aligning ball bearing whose internal bore surface is tapered. The tapering is :2: 3. Closed type (Fig. 3) Self aligning ball bearing with sealing rings on both sides: 2. Permitted self aligning angle The internal structure design of self aligning ball bearings enable them the self aligning function, which can make the bearings correct the angle alignment errors between the inner and outer races by themselves. In normal load and working conditions, the misalignment angle values given in Table are permitted when the inner race is running. Whether the given values can be reached completely also depends on the design and sealing types of the reference bearing structures. etc. 3. Retainer The retainers of self aligning ball bearings often adopt either stamped steel or glass fiber reinforced nylon. If self aligning ball bearings with nylon retainers are required, please consult the technical center of DPI. 4. Radial Clearance DPI standard type cyiindrical bore self aligning ball bearings adopt conventional set clearance. Taper self aligning ball bearings take C3 set clearance as standard type. Self aligning ball bearings with clearance greater that or less than standarddized set can be provided on request. The clearance of inner race lenghthened self aligning ball bearings is between C2 set and conventional set. 5. Scale accuracy & running load DPI can also provide various self aligning ball bearings above the ordinary grade of the technical specification for relevant dimensional precision and running accuracy. 6. Dynamic equivalent load When Fa/Fr > e, P=0.65Fr + Y2Fa The relevant calculating coefficient e Y and Y2 for each bearing can be found in the dimension table. 7. Static equivalent load Bearing series The coefficient value YO for each bearing has been given in the dimension table.

05 Cylindrical Roller Bearing These bearings require feature high radial load as rollers and raceway are in linear contact. These are ideal for applications where there is heavy impact or radial loading. Due their construction they can be very accurately machined and hence are also used in high speed applications. An additional feature of these bearings is that they have a seperable inner and outer ring due to which mounting and dismounting is very easy. The following types of Cylindrical roller bearings are available:. Single Row Cylindrical Roller Bearings: Cylindrical Roller Bearings Within this type they are further subdivided as follows: a) NU & N Type: These give good performance when they are used as free side bearings as they adjust to the shafts axial movement to a certain extent. b)nj & NF Type: These carry axial load in one direction c) NUP & NH Type: These can carry a certain degree of axial load in both directions. 2. Four point contact ball bearings These have a contact angle of degrees. The inner ring is divided into 2 pieces. These are very specialized bearings. The standard cages used are pressed steel cages. Additionally Copper alloy machined cages are also available. For details on boundary dimensions and specifications please refer to the tables overleaf. 93

05 Cylindrical Roller Bearing Cylindrical roller bearing The rollers of cylindrical roller bearings are often guided by two ribs of a certain ring. The retainer, roller and guide ring make up an assembly. It can be seperated from another ring. They are separable bearings. They are easy to mount and dismount. Especially when tight fit is required for the inner/outer race and the axle/ shell, their advantages are more obvious. This type of bearings is often used to bear radial load. Only single row bearings with ribs on both inner and outer races can bear low constant axial load or high interval axial load. Compared with deep groove ball bearings of same physical dimensions, this type of bearings radial loading capacity is larger. The requirements for the working accuracy of the axles and shell bores for this type of bearings is higher.. Primary structure type Outer race without rib, inner race with tworibs N type Outer race without rib, inner race with two ribs NU type Outer race with single rib, inner race with two ribs NF type 2. Permitted inclination angle Generally the axle of the cylindrical roller bearings is not permitted to incline to the outer bore. But, when the load is light, the axial directions of the inner and outer races of the single row cylindrical roller bearings are permitted to incline 2 mutually. If the load is heavier, the permissible error is also larger, but is not permitted to exceed 4. 3. Tolerance and clearance Outer race without rib, inner race with single rib NU type Outer race with two ribs, inner race with single rib and a plate NUp type The retainers of bearing of the above structures often include: Pressed structure, nylon fabric, etc. Some models can be full of rollers without retainers. As required, products of different grades of tolerance can be provided. See the above section tolerance for the tolerance values. 4. Axial load capacity For cylindrical roller bearings with inner and outer races, their axial load is related to radial load the bear and the lubricating methods. imum permitted axial load. F ap = KC 0r ( n g n ) n g 2n F ap < 0.4F r Oil n F ap = KC 0r ( g 2.5n ) Grease n g 0n In the equations: Fap: imum permitted axial load N K: Coefficient relating to the bearing dimensions series For 2,3 series K=0.2 22,33 series k=0.6 COr: Static radial load rating of bearings N Ng:The limit speed when the bearing bears radial load, when Fr > 0.Cr, the limit speeds listed in the dimension table shall be multiplied by the decreasing coefficient r/min. N: Bearing working speed r/min The axial load determined by the above formula acan make Grade 0 tolerance bearing (except improved and reinforced bearings) work normally in the following conditions. Bearing temperature rise is 55 C for oil lubrication and C for grease lubrication. The bearing maximum temperature is 90 C ( the used lubricating oil viscosity is V50=33mm2/s and the drop point of grease is 70 C). For interval axial load, the permitted axial load can be improved time and for transient one, it can be improved 2 times. According to the working conditions, single row cylindrical roller bearings with lareger axial load capacity can be provided. 5.

06 Tapered Roller Bearing Tapered roller bearings have tapered surfaces whose apexes converge at a common point on the bearing axis. This type of bearing is suitable for applications involving heavy or impact loading. Single Row Tapered Roller Bearings Single row tapered roller bearings are able to carry axial and radial load in one direction simultaneously. Tapered Roller Bearings 3

06 Tapered Roller Bearing Taper Roller Bearing Taper roller bearings are mainly used to bear radial and axial combined loading (mainly radial), large taper angle taper roller bearing can be used to bear radial and axial combined loading (mainly axial). These bearings are separate type bearings, whose inner race components (including taper roller and retainer) and outer space can be mounted respectively. During mounting and use, the radial clearance and axial clearance of the bearings can be adjusted, and premounting is also possible.. Main structure types.singlerow taper roller bearing 000 This type of bearings can limit the axial displacement of shaft and housing in one direction, and bear axial road from one direction. Affected by radial load, they will generated additional axial force, and are generally used in pairs in the two bearers of the shaft. 30 series taper roller bearings have large contact angles (27 ), and can generate large axial load. The contact angels of the other bearings of other series are between 08. 2. Permitted inclination angle If the contact state of the roller ring is proper, it cannot only prevent the abnormal margin load of contact surface, but can also allow the inner/outer race inclination caused by alignment error, etc. The permitted inclination angles of taper roller bearings are generally 0.0005rad (.5 ) for backtoback combination, and 0.00rad (.5 ) for facetoface combination. Please contact the technical center of DPI if larger inclination angles are required. direction of the applied axial load. The additional axial force of singlerow taper roller bearings can be approximately calculated according to the following formula: S= Fr/2Y 5. Static equivalent radial load Single row taper roller bearing P0r=Fr+Y0Fa if P0r<Fr adopt P0r = F Fr and Fa both refer to the total load applied to single row and double row bearings. See the bearing dimension table for the calculating coefficients e,y,y,y2, and Y0. 6. imal radial load In order to prevent the rolling between roller and raceway caused by inertial force of roller and retainer during the high speed running of the bearing, the bearing must carry certain load, and its minimum value can be estimated according to the following formula: Frmin = Cr In the equations: Frmin: imal radial load KN Cr: Basic dynamic load rating KN 3. Tolerance and clearance Taper roller bearings with different kinds of tolerance grades can be manufactured as required. Customers can adjust the clearances of single rowtaper roller bearings at the time of mounting as required. The radial clearance of Double row taper roller bearings can be the antecedent tolerance and clearance section according to customer requirements. Customers can adjust clearance according to related procedures during as required. 4. Dynamic equivalent radial load Single row taper roller bearing: Pr = Fr (when Fa/Fr>e) Pr = 0.4Fr +YFa (when Fa/Fr>e) Single row taper roller bearings (principal dimensions may be different) are used in pairs, the additional axial force caused by radial load must be taken into account while calculating the dynamic equivalent of the bearing. The axial load magnitude of the bearing is related to its installation configuration mode and the 4 5

08 Thrust Ball & Roller Bearing Thrust ball bearings are divided into two types:. Single Direction Thrust Bearings These can accomodate axial load in one direction. 2. Double Direction Thrust Bearings These can accomodate axial load in both directions. Thrust bearings are not suitable for applications which require high speed or radial load. The standard cages used are pressed steel cages or with copper alloy machined cage and in some cases also have molded cages.

This permits selfaligning between the two members. Above figure is a view of a Pillow Block which is the most popular type of Insert Ball Bearing Units with set crew locking. The bearing units have various types of perfect sealing devices and can operate satisfactorily under hardworking conditions, especially for machines operated in dusty or muddy surroundings. Thus, they are widely used in agricultural machinery, construction machinery, textile machinery, foodstuff machinery and conveying devices, etc. Note:. When the fit between bearing and housing is clearance fit, the bearing s outer ring has antirotation ball (pin). 2. Two set screws on the wide inner ring at C apart. 3. Usually, The Outer ring of the DPI Bearings had grease groove, bearing having no grease groove are to be provided too. 9

Insert Ball Bearing Units The Features of Products Insert Ball Bearing Units Rational Self Alignment The outside diameter of the selfcontained bearing is spherical to match corresponding spherical inside diameter of the housing providing self aligning between these two members, which compensates for misalignments of the units resulted from errors in mounting and distorting of the foundation. Housings Bearings P.PK, LP PA,PG,PAA F,FU Cast Iron Housings Pressed Steel Plate Housing FL,FLU LF,FD FC T,ST,K PP PFL PF PFT Large load carrying capacity Being the same as 60 and 60 series single row deep groove ball bearing in internal construction of the the selfcontained bearings, Insert ball bearing units can sustain radial loads and sustain thrust loads as well. And they are low noise during operating. Longer Service Life Insert ball bearing units are often used in severe operating conditions where they are exposed to dirts,moisture and high temperature and in such applications, the grease inside the selfcontained bearing deteriorates in a short time. It is required that relubricate the units at suitable intervals so as to replace deteriorating grease with fresh grease. Insert ball bearing units with east iron housings are all relubricable types equipped with grease fitting to secure full performance and longer service life of the units under any operating conditions.
