Thrust ball bearings are separate-type bearings that can only withstand axial loads and cannot withstand radial loads. They are available in two configurations: single-direction and double-direction; the single-direction type withstands axial forces in one direction, whilst the double-direction type can withstand axial forces in both directions. They have a relatively low maximum speed and lack self-aligning capability. They are commonly used in support positions subject to axial loads, such as machine tool spindles, pumps, valves and low-speed transmission mechanisms.
