Spherical Roller Bearing 22315CA/W33

Spherical roller bearings in the two groove of the inner ring and the outer ring raceway is spherical, with drum shaped roller bearing assembly.

 

Spherical roller bearing with two rows of rollers, mainly bear radial load, but also can bear the axial load in either direction. A high radial load capacity, especially suitable for heavy load or loads, but unable to bear the pure axial load. This type of bearing outer ring raceway is spherical in shape, so the good aligning performance, can compensate the coaxiality error.

 

[1] has two rows of symmetrical spherical roller, the outer ring has a common spherical raceway, race two and the bearing axis tilt angle raceway, having good aligning performance, when the shaft is bent by force or not installed concentric bearing can be normal use, adjustable concentric with the bearing size series vary, in general allow aligning angle of 1~2.5 degrees, the types of the load bearing capacity of large, can bear radial load bearing can withstand a bi-directional axial load, has good shock resistance capability, generally spherical roller bearings are allowed to work in low speed.

 

Spherical roller bearing press roller section shape is divided into a symmetrical spherical roller and non symmetrical spherical roller of two different structure, non symmetrical spherical roller bearing is the early products, is now the main host for the repair service, the new design is rarely chosen host symmetrical spherical roller bearing, internal structure through comprehensive improvement design and parameter optimization, and early production spherical roller bearing, can bear bigger axial load, the bearing running at a lower temperature, it can be adapted to higher speed requirements, according to the inner ring has no blocking edge and the retainer can be classified into type C and type CA two, C type bearing characteristic is flangeless inner ring and use of steel stamping cage, type CA Train bearing characteristics for both sides of the inner ring rib and car business entity retainer in order to improve the lubrication of the bearing, the outer ring can be provided to users with an annular oil groove and three oil holes to bearing self-aligning roller bearing, post code /W33 said, according to user requirements can also be the supply of oil hole of spherical roller bearing with inner ring, in order to facilitate customer handling and replacement of bearings, can also be provided with taper bore of spherical roller bearing, taper Taper for 1:12 is codenamed K said, in order to meet the special requirements of users may also be provided with taper bore for 1:30 bearing, its post code-named K30 bore tapered bearing available lock nut bearing is directly mounted on the tapered shaft neck, or with the help of the tight sets or withdrawal sleeve bearing mounted in a cylindrical shaft neck. In order to ensure the bearing during high speed operation of centrifugal effect in prevent the raceway and roller between the harmful slip, bearing should bear a certain minimum radial load can be pressed type estimation:

 

Fr =0.02C

 

Type of

 

Fr - minimum radial load N

 

C - bearing basic dynamic load rating N

 

Equivalent dynamic load

 

When Fa/Fr e P=Fr+Y1Fa

 

When Fa/Fr e P=0.67Fr+Y2Fa

 

Type of

 

P - equivalent dynamic load N

 

Y1 Y2 - axial dynamic load coefficient

 

Equivalent static load

 

P0=Fr+Y0Fa

 

Type of

 

P0 - equivalent static load N

 

Y0 - static thrust load factor
