Thrust Roller Bearings | KG International FZCO

Spherical Roller Thrust Bearing is a self-aligning bearing. In service, it allows a maximum shaft misalignment of about 2 degrees. The contact angle helps this type of bearing to handle a small amount of radial load. Lubriion of these bearings needs to be done carefully since their large sliding contact area results in smearing.
