Five Basic Properties of China Spherical Roller Bearings

Wear-resisting property of China Spherical roller bearing


When the spherical roller bearing works, there is not only rolling friction but also sliding friction between the ring, the roller and the cage, so that the bearing parts will continue to wear. In order to reduce the wear of bearing parts, maintain the stability of bearing precision and prolong the service life, the bearing steel used in China spherical roller bearings has good wear resistance.


Contact fatigue strength of China Spherical roller bearing


Under the action of periodic load, fatigue damage is easily to occur on the contact surface of the bearing, that is, cracking and spalling, which are the main forms of bearing damage. Therefore, in order to improve the service life of bearings, the bearing steel used in China spherical roller bearings must have very high contact fatigue strength.


Hardness of China Spherical roller bearing


Hardness is one of the important qualities of bearings, which has a direct influence on contact fatigue strength, wear resistance and elastic limit. In order to obtain high contact fatigue strength and wear resistance, the hardness of China spherical roller bearing in service state should generally reach HRC61-65.


Anti-corrosion performance of China Spherical roller bearing


In order to prevent bearing parts and finished products from being corroded and rusted in the processing, storage and use, bearing steel is required to have good anti-corrosion performance.


Processability of China Spherical roller bearing


In the production process, bearing parts have to go through many cold and hot processes. In order to meet the requirements of multitudinous, high-efficient and high-quality production, China spherical roller bearings are used with good processability, such as cold and hot forming performance, cutting performance and hardenability.
