Heat treatment process is an important technology in the field of metal processing. It mainly changes the internal structure of the material by controlling the heating, insulation and cooling processes of the material, thereby achieving the purpose of improving material performance, improving material processing performance or solving internal defects of the material.

There are more than 70 complete production steps for a bearing. The main processes and processes are introduced here to help us have a general understanding of the bearing production process.

Bearing steel is widely used in various fields such as industrial machinery, equipment manufacturing, transportation, aerospace and so on. In different fields, the working conditions and application environments of bearings are different. Therefore, different bearing steel materials need to be selected.

The quality of bearings is affected by many factors such as materials, heat treatment, raceway and rolling element design, lubrication and machining accuracy.
