Thrust ball bearings are a type of rolling-element bearing designed specifically to handle axial loads while operating at moderate to high speeds. They consist of two raceways, a set of precision steel balls, and a cage to maintain ball separation. These bearings are classified into **single-direction** (handling loads in one direction) and **double-direction** (handling loads in both directions) types. Commonly used in applications like automotive clutches, turbines, and industrial machinery, thrust ball bearings are valued for their smooth operation, low friction, and ability to support high axial forces with precision.
