Characteristics of bearing steel:(1)
Dec 05, 2018

I. Contact fatigue strength
Under the action of periodic load, the bearing is easy to suffer from fatigue damage, that is, cracking and peeling, which is an important destructive situation of the bearing. Therefore, in order to improve the service life of bearings, bearing steel must have high contact fatigue strength.
Two. Wear resistance
During the bearing task, not only rolling friction but also sliding friction occurs between the ring, the rolling element and the maintainer, which makes the bearing parts wear all the time. In order to increase the wear of bearing parts, maintain the accuracy and stability of bearings, and extend the service life, bearing steel should have good wear resistance.
