A rolling bearing is a precision mechanical component that changes the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing friction losses. 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 element is The cage evenly distributes the rolling elements between the inner ring and the outer ring. Its shape, size and number directly affect the performance and life of the rolling bearing. The cage can evenly distribute the rolling elements, prevent the rolling elements from falling off, and guide the rolling elements. Rotation provides lubrication.

In the processing of bearing parts, a large number of bearing-specific equipment are used. For example, steel ball processing uses ball mills, grinders and other equipment. Specialization is also reflected in the production of bearing parts, such as steel ball companies specializing in the production of steel balls, and micro bearing factories specializing in the production of micro bearings.

Advancedness

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

automation

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

According to the structure, rolling bearings can be divided into: deep groove ball bearings, needle roller bearings, angular contact bearings, aligning ball bearings, spherical roller bearings, thrust ball bearings, thrust spherical roller bearings, cylindrical roller bearings, tapered rollers Bearings, seated spherical ball bearings, etc.
