High-carbon chromium bearing steel is the most common material for bearings. The main factor is that it can have high hardness and accuracy under many conditions of operation, and balance the relationship between stress and material fatigue. The main factors affecting the life, in addition to the external use conditions, the internal metal element composition is also very important, non-metallic intermediaries and the reduction and reduction of oxygen content control, need to rely on the actual implementation of steelmaking technology and heat treatment. In addition, under special working environment requirements, we also have stainless steel or ceramic ball bearings to choose from, as well as continuous research and development of surface corrosion-resistant coating technology, the purpose is to find the most suitable product material for customers.
