What are the five major advantages of bearing steel?

With the needs of social needs, more and more materials used in bearings will use bearing steel, such as steel balls, steel rings, etc. Nowadays, our country has also made certain breakthroughs in high-end bearing steel. It is self-sufficient and can also export, which will be of certain help to our country's high-end bearing equipment. But many people still don’t know what are the advantages of bearing steel materials?

Bearing material - five major advantages of bearing steel:

1. Contact fatigue strength
Under the action of cyclic loads, bearings are prone to fatigue damage on the contact surface, that is, cracking and peeling, which is the main damage form of bearings. Therefore, in order to improve the service life of the bearing, the bearing steel must have high contact fatigue strength.

2. Wear resistance
When the bearing is working, not only rolling friction but also sliding friction occurs between the rings, rolling elements and cages, causing constant wear of the bearing parts. In order to reduce the wear of bearing parts, maintain bearing accuracy and stability, and extend service life, bearing steel should have good wear resistance.

3. Hardness
Hardness is one of the important qualities of bearings and has an indirect impact on contact fatigue strength, wear resistance and elastic limit. The hardness of bearing steel under use conditions generally needs to reach HRC61~65, so that the bearing can obtain high contact fatigue strength and wear resistance.

4. Anti-rust performance
In order to prevent bearing parts and finished products from being corroded and rusted during processing, storage and use, bearing steel is required to have good anti-rust properties.

5. Processing performance
During the production process, bearing parts must go through many cold and hot processing processes. In order to meet the requirements of small quantity, high efficiency and high quality, bearing steel should have good processing properties. For example, cold and hot forming properties, cutting performance, hardenability, etc.
