Thrust ball bearings

Thrust ball bearings are divided into two categories: unidirectional thrust ball bearings and bidirectional thrust ball bearings.
Unidirectional thrust ball bearing:
Unidirectional thrust ball bearings are separable bearings. Composed of a combination of a shaft ring, a seat ring, a ball, and a cage. Installation and disassembly are both very convenient. The ring that fits tightly with the shaft is called a shaft ring, and the ring that has a gap with the shaft is called a seat ring. Unidirectional thrust ball bearings can only withstand unidirectional axial loads and cannot withstand any radial loads, and can be used for unidirectional axial positioning of the shaft.
Due to the inability to restrict radial movement between the shaft and the housing hole, the limit speed is relatively low. When the axis of the shaft and the bearing seat hole do not coincide or the bearing support surface is not perpendicular to the axis, it will cause premature damage to the bearing. If such a situation occurs, a thrust ball bearing with a spherical seat ring can be used to compensate for the angle error between the bearing housing and the thrust ball bearing.
Bidirectional thrust ball bearings:
Bidirectional thrust ball bearings are separable bearings. It consists of a shaft ring with grooves on both sides, two seat rings, and two ball and cage assemblies. Bidirectional thrust ball bearings can withstand axial loads acting in both directions, but cannot withstand any radial loads. Therefore, bidirectional axial positioning of the shaft is possible.
The seat ring and ball cage components are the same as the corresponding one-way bearings.
