We have all kinds of bearings, so naturally, there will be a bearing supplier . Today we take a look at the characteristics of bearing steel.

Hardness is one of the important qualities of bearing quality, and has an indirect influence on contact fatigue strength, wear resistance, and elastic limit. The hardness of bearing steel under operating conditions must reach HRC61~65, which enables the bearing to achieve higher contact fatigue strength and wear resistance.

To prevent bearing parts and finished products from being corroded and rusted during processing, storage, and use, it is requested that the bearing steel should have good rust resistance.

In the production process, bearing parts have to go through many cold and hot processing procedures. To satisfy the small quantity, high efficiency, and high-quality requirements, the bearing steel should have good processing performance. For example, cold and hot forming performance, cutting performance, hardenability, and so on.

In addition to the above-mentioned basic requirements, bearing steel should also meet the requirements of proper chemical composition, average external structure, less non-metallic inclusions, external appearance defects conforming to specifications, and external surface decarburization layer not exceeding the regular concentration.
