Deep Groove Ball Bearing 8*22*7mm

1, Contact fatigue strength Under the action of periodic loads, bearings are prone to fatigue damage on the contact surface, resulting in cracking and peeling, which is an important damage situation for bearings.  Therefore, in order to improve the service life of bearings, bearing steel must have high contact fatigue strength.

2, Wear resistance During the bearing task, not only rolling friction occurs between the ring, rolling element, and maintenance bracket, but also sliding friction, resulting in continuous wear of the bearing parts.  In order to increase the wear of bearing parts, maintain bearing accuracy and stability, and extend service life, bearing steel should have good wear resistance.
