Thrust ball bearings can be separable. Thrust ball bearings have the following features：
1. Contact angle of thrust ball bearing is 90 degrees, and it can only withstand axial load. The unidirectional thrust ball bearing can only bear the axial load in one direction and the bidirectional thrust ball bearing can bear the axial load in two directions.
2. The steel ball of thrust ball bearing is pushed to the outside of the raceway due to centrifugal force, so it is not suitable for high-speed operation.
3. The thrust ball bearing with spherical seat ring has the self-aligning ability, which can eliminate the influence of installation error.
