ZWRZ Big Type Self-aligning roller bearing 23940

1.Spherically can make selfalingnment,. 2.Rolling elemtnts linearly come into contact with the raceways of inner and outer ring

1,Dimension

Overall dimension of bearing listed in beaing table accords to ISO015-1981.

2,Angular alignment tolerance

Self-aligning roller bearing is designed in such a way that it is self-aligning.That means that bearing can adjust itself and angular alignment tolerance between outer rings.Under normal load and working condition and inner ring rotates,the unsymmetrical value listed in below table is allowed.Achieving completely specifide value is subject to design and seal type of configured bearing.

3,Tolerance

The self-anligning roller bearing with cylindrical bore or tapered core is of common tolerance level .

4,Internal clearance

 According to the ZWRZ standard,self-aligning roller bearing is of common tolerance level in internal clearance in its radial direction.Almost all bearings can be supplied at C3 clearance,or even higher level C4 clearance.Bearings with dimension less than common level:C2 clearance can also be supplide.Please consult first to check supply status for bearing with non-standard radial clearance (includingC5).These clearance values are used for zero load testing and shaft,which remains uninstalled.

Besides CA type, we can provide CC and MB structure for special clients.
