The thrust bearing is a rolling bearing. Although they allow rotation between parts similar to other bearings, thrust bearings are primarily designed to support axial loads. Thrust roller bearings help to reduce friction and cope with pressure, while enabling the various parts of automobiles and other machinery to rotate or move linearly. Metal to metal contact will produce a lot of friction and stress in the metal. This friction usually increases the premature wear of the metal while slowly degrading it. The main function of thrust roller bearing is to reduce this friction, so that metal parts can work smoothly, thus extending its durability. Some functions of the lower thrust roller bearing are described below.

The thrust roller bearing mainly has the following functions:

1、The function of the bearing is to fix the shaft so that it can only rotate, thus controlling its axial and radial movement. The shaft can move in any direction, but it is required that the shaft can only rotate when the motor is working, so the motor cannot work without bearings.

2、Lubrication function: the lubrication purpose of rolling bearing can reduce the internal friction and wear of bearing, avoid burning and sticking, and increase its service life; Discharge friction heat and cooling to prevent bearing from being too hot, prevent lubricating oil from aging, foreign matters from invading the bearing, or prevent rust and corrosion.

Precautions for thrust roller bearing: 1. Distinguish the tight ring and loose ring of the bearing. 2. Distinguish the static parts of the mechanism. 3. The loose ring of the bearing should always rest on the end face of the stationary part.
