Bearing Arrangement - an overview | ScienceDirect Topics

Thrust bearing, Fig 3.12A, composed of bearing balls supported in a ring, these can be used in low thrust appliions where there is relatively small axial load, but are susceptible to radial loads. Tapered roller thrust bearings, Fig 3.12B, consist of small tapered rollers arranged so that their axes all converge at a point on the axis of the bearing.
