Rolling bearings generally consist of four parts: inner ring, outer ring, rolling elements and cage.

The function of the inner ring is to cooperate with the shaft and rotate together with the shaft; the function of the outer ring is to cooperate with the bearing seat and play a supporting role; the rolling elements are evenly distributed between the inner ring and the outer ring by means of the cage, Its shape, size and quantity directly affect the performance and life of the rolling bearing; the cage can evenly distribute the rolling elements and prevent the rolling elements from falling off.

Rolling bearing features are as follows:

In the processing of bearing parts, a large number of special equipment for bearings are used, such as ball mills for steel ball processing. Specialization is also reflected in the production of bearing parts, such as steel ball companies specializing in the production of steel balls, miniature bearing factories specializing in the production of miniature bearings, etc

Due to the large-scale requirements of bearing production, it is possible to use advanced machine tools, tooling and processes. Such as CNC machine tools, three-jaw floating chuck and protective atmosphere heat treatment, etc.

The specialization of bearing production provides conditions for its production automation. A large number of fully automatic, semi-automatic special and non-special machine tools are used in production, and the production automatic line is gradually promoted and applied. Such as heat treatment automatic line and assembly automatic line, etc.
