Thrust Ball Bearing

Thrust ball bearing is composed of shaft ring, seat ring, steel ball and cage. The ferrule matching with shaft is called shaft ring, and the ferrule matching with shell is called seat ring. The bearing with spherical mounting surface of seat ring has centering performance, which can reduce the impact of installation error.

>>Structure & Characteristic

结构图

According to different structures, thrust ball bearings can be divided into two types:

  1. Single direction thrust ball bearing
  2. Double direction thrust ball bearing

1. Single direction thrust ball bearing

It includes a shaft ring, a seat ring and a ball cage assembly. The bearing can be separated, and the shaft ring, seat ring, steel ball cage assembly can be installed separately. There are three types:

  1. Thrust ball bearing with flat race
  2. Thrust ball bearing with aligning race
  3. Thrust ball bearing with aligning seat ring and aligning seat washer

The single direction thrust ball bearing is mainly used to bear the one-way axial load, and can make the single direction axial positioning.

2.Double direction thrust ball bearing

It includes a shaft ring, two seat rings, a central shaft ring and a ball cage assembly. The bearing can be separated, and the shaft ring, seat ring, steel ball cage assembly can be installed separately. There are three types:

  1. Thrust ball bearing with flat race
  2. Thrust ball bearing with aligning race
  3. Thrust ball bearing with aligning seat ring and aligning seat washer

The double direction thrust ball bearing can bear two-way axial load and make two-way axial positioning.

>>Application

应用

Thrust ball bearing is mainly used to bear axial load, which can transfer large axial load, but can not bear radial load. These bearings are mainly used in automobile steering mechanism, machine tool spindle, etc.
