Bearing is a component that fixes, rotates, and reduces the coefficient of friction of the load during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, the mechanism for reducing the friction coefficient during the transmission of the moving force and keeping the center position of the rotating shaft fixed.
Bearings are a very important part of contemporary machinery. Its main function is to support the mechanical rotating body to reduce the mechanical load friction coefficient of the equipment during the transmission process. Its accuracy, performance, life and reliability play a decisive role in the accuracy, performance, life and reliability of the main engine. . According to the friction properties of the moving parts, the bearings can be divided into two types: rolling bearings and sliding bearings.

2. The four major parts of the rolling bearing:
◆ The inner ring is usually tightly fitted with the shaft and rotates with the shaft.
◆The outer ring usually cooperates with the housing hole or the housing of the mechanical component to support.
◆The rolling elements are evenly arranged between the inner and outer rings by means of the cage, and its row shape, size and number directly determine the bearing capacity of the bearing.
◆ The cage separates the rolling elements evenly and guides the rolling elements to move on the correct track.
