What are the tapered roller bearings?
General use of chromium alloy steel manufacturing, commonly used materials are GCr15, GCr15SiMn, GCr6, GCr9, etc., after heat treatment, hardness of up to HRC61-65.
Tapered roller bearings commonly used materials: rolling and internal and external ring materials require high hardness and contact fatigue strength, good wear resistance and impact toughness.
Cages are usually made of low carbon steel sheets, and high speed bearings are made of non-ferrous metals (such as brass) or plastic cages.
