Test and Analysis of Dimensional Change of Carburized Steel Ring after Heat Treatment
Bearing ferrules are highly susceptible to deformation during heat treatment, a problem that is common in the bearing manufacturing industry. Because there are many uncertain factors affecting the deformation and dimensional change of the ferrule, and it is difficult to solve, it has become a major obstacle to the continuous development of bearing products. The bearing components are quenched to obtain good structure and sufficient strength. Some quality problems such as uneven hardness, deformation, and dimensional changes are likely to occur during quenching. During this heat treatment process, there are more uncertain factors affecting the deformation and dimensional change of the ferrule, and the size of the ferrule changes.
