Overview of thrust ball bearings

Thrust ball bearings are composed of three parts: seat ring, shaft ring and steel ball cage assembly. The one that matches the shaft is called the shaft ring, and the one that matches the shell is called the seat ring.

According to the force analysis, they are divided into one-way thrust ball bearings and two-way thrust ball bearings. One-way thrust ball bearings can withstand one-way axial load. Bidirectional thrust ball bearings can withstand bidirectional axial loads, in which the shaft ring matches the shaft. The mounting surface of the seat ring is a spherical bearing, which has self-aligning performance and can reduce the impact of installation errors. Thrust ball bearings cannot bear radial loads, and their limit speed is relatively low.
