Spherical Roller Thrust Bearings are separable single direction acting axial

bearings (see sketch below). Spherical roller thrust bearings are selfaligning as their spherical rollers run on the spheroid raceways of shaft and housing washers.

Therefore they are well able to accommodate errors of misalignment and some shaft bending in an optimum way.

Spherical roller thrust bearings transmit forces via a contact angle towards the centre axis. Thus, they are able to accommodate some radial forces along with high axial loads. But, it must be considered that the actingradial forces must not exceed approximately 55 % of the applied axial forces.
