Thrust ball bearings consist of washer shaped rings with raceways, rolling elements, and retainers, and are divided into two types: unidirectional and bidirectional. Unidirectional thrust ball bearings can only withstand unidirectional axial loads, while bidirectional thrust ball bearings can withstand bidirectional axial loads. The rolling elements of this bearing have a small contact area with the raceway, low frictional resistance, and can achieve efficient axial rotation. However, due to its structural characteristics, it is not suitable for bearing radial loads. Thrust ball bearings are commonly used in equipment such as machine tool spindles, automotive gearboxes, and crane hooks that require precise axial positioning and axial force bearing, ensuring stable operation in the axial direction in mechanical transmission systems.
