[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. In the process of bearing processing and manufacturing, they often need to be heat treated, which is a metal heat processing process to obtain the expected structure and performance through heating, insulation and cooling. In general, the bearings are stacked in a frame during heat treatment, and then hoisted into a heating well by a crane for heat treatment. However, this stacking method often has poor heat conduction effect, which affects the efficiency of heat treatment processing. Therefore, a steel bearing heat treatment frame is proposed.
