Bearings are an indispensable component of mechanical equipment. Their function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Bearings are subjected to great pressure and friction when working, so they need to have specific properties to meet usage requirements. As the main material of forged bearings, the quality of bearing steel directly determines the performance and service life of the bearing.

Heat treatment is a very important link in the material processing process. It changes the internal structure of the material by controlling the heating, insulation and cooling processes, thereby improving its performance.
