Product Details

1.Hardness Hardness is one of the important qualities of bearing quality, which indirectly affects contact fatigue strength, wear resistance, and elastic limit. The hardness of bearing steel under operating conditions should reach HRC61~65, which enables the bearing to achieve high contact fatigue strength and wear resistance.

2. Rust prevention performance In order to avoid corrosion and rusting of bearing parts and finished products during processing, storage, and use, it is requested that bearing steel should have good rust prevention performance.

3.Processing performance In the consumption process of bearing parts, there are many cold and hot processing processes. In order to meet the requirements of small quantities, high efficiency, and high quality, bearing steel should have good processing performance. For example, cold and hot forming performance, cutting performance, hardenability, etc.
