Thrust ball bearings are designed to withstand thrust loads at high speeds and consist of a washer-like ferrule with ball rolling groove grooves. Since the ferrule is in the shape of a seat cushion, the thrust ball bearing is divided into two types: a flat base cushion type and a self-aligning spherical seat cushion type. In addition, this bearing can withstand axial loads but cannot withstand radial loads.

Thrust ball bearing composition: Thrust ball bearing is composed of three parts: seat ring, shaft ring and steel ball cage assembly. The so-called shaft ring that cooperates with the shaft, and the seat ring that cooperates with the outer casing.

species:

According to the force condition, the one-way thrust ball bearing and the two-way thrust ball bearing are divided.

One-way thrust ball bearings can withstand one-way axial loads. The two-way thrust ball bearing can withstand two-way axial load, in which the shaft ring is matched with the shaft. The mounting surface of the seat is spherical and has a self-aligning performance, which can reduce the influence of installation errors. Thrust ball bearings cannot withstand radial loads and have lower limit speeds.
