Description

Thrust Roller Bearings The angle created between the bearing axis and the line of contact between the raceway and the tapered roller determines the degree of thrust this bearing can accommodate. If this angle is greater than 45°, the bearing is better suited for axial loads. Once the angle between the bearing axis and roller axis reaches 90° the bearing can only sustain axial loads. These bearings require a cage, and sometimes a flange, to retain the roller assembly.
