Thrust ball bearings are also called thrust bearings, it is one of particular separable ball bearings, they are composed of shaft washer,housing washer and steel balls with cage. And shaft washer is designed to fix the shaft, and housing washer is designed to fix the parts outside the shaft. As opposed to deep groove ball bearing, thrust ball bearing can only support axial load and medium speed. As opposed to deep groove ball bearing, thrust ball bearing can only support axial load and medium speed. According to the force direction,thrust ball bearing are divided into unidirectional thrust ball bearings (one-way thrust ball bearing) and bidirectional thrust ball bearing(two-way thrust ball bearing). Unidirectional thrust ball bearing can only support unidirectional axial load. And bidirectional thrust ball bearing can support bidirectional axial load. Thrust ball bearings are widely used in crane hook, vertical water pump, vertical centrifuge, Jack, low-speed reducer which only need one side of axial load and low speed.
