Overview

Spherical roller thrust bearing with stamped steel cage

Spherical roller thrust bearings accommodate very heavy axial and considerable radial loads. They have the highest load rating of all thrust bearings, enabling compact, high power density bearing arrangements. By combining two or more spherical roller thrust bearings, it is possible to create a bearing arrangement that is either self-aligning, allowing misalignment of the shaft, or very stiff.

Key features

High load carrying capacity
Can accommodate combined loads
Allow misalignment or create very stiff bearing arrangements
Long service life and low friction
Separable design

Typical applications

Motors, pumps, and fans
Reducers and industrial gearboxes
Conveyors and handling equipment
General industrial machinery maintenance

Selection guidance
