What material does the bearing generally use


30th January 2010 Bearing Technology 0 Comments

What the bearing is generally used is high-carbon steel GCr15, the bearing steel that commonly called as. Other things are also bearing steel, high temperature resistant bearing steels, shock-resistant bearing steels of middle carbon, the newest bearing material is the pottery now
On the whole the bearing materials degree has six major requirements
First, it is exposed to big fatigue strength that rolling
Second, the pure degree of material is high
Third, can get the high even hardness through the heat treatment
Fourth, high wearability
Fifth, size stability is good
Sixth, there is the better one that is able to bear corrosivity and chemical stability
Use chromium steel, chromium molybdenum steel, nickel chromium molybdenum steel, adopt and ooze the charcoal to quench as the bearing material, make steel from surface to having one the intersection of sclerosis and layer deeply appropriate. Oozing the charcoal bearing of the surface with appropriate sclerosis depth, close tissue, suitable hardness and hardness of core, have fine impact resistance more than the bearing which use the bearing steel, the general one oozes the chemical composition of using steel of the charcoal bearing.
