Ball thrust bearings suit high-speed applications and light loads for high precision applications.

The thrust ball bearing is designed to withstand the thrust load during high-speed operation, and is composed of a washer shaped ring with a ball rolling raceway groove. As the race is cushion type, thrust ball bearings are divided into two types: flat bottom cushion type and self-aligning spherical cushion type. In addition, the bearing can bear axial load, but cannot bear radial load.

There are two types of thrust ball bearings: one-way and two-way. One way thrust ball bearing is composed of two rings (shaft ring and bearing race) and a retaining structure with a ball. The bi-directional thrust ball bearing is composed of three rings and two retaining structures with balls. In case of two-way type, the shaft ring is clamped by two cages with balls.

Characteristic
1. Available in one-way and two-way
2. In order to allow installation error, spherical self-aligning spherical seat cushion type or spherical seat ring type can be selected regardless of one-way or two-way

One way thrust ball bearing
The ball bearing can bear axial load in one direction.

Two way thrust ball bearing
The ball bearing can bear the axial load upward on both sides.
