Ring and rolling body material: ring and rolling body usually use high carbon chromium bearing steel.
Most of the bearing, using JIS the SUJ2 steel grade, is domestic chrome steel (
GCr15)
。
The chemical composition of SUJ2, around the world, as a bearing material has been normalized.
For example: with AISL52100 (
The United States)
DIN100Cr6 (
West Germany)
BS535A99 (
The UK)
All belong to the same steel.
The steel grade, according to the special purpose, also use the excellent heat resistance of high speed steel, good corrosion resistance of stainless steel.
Detailed visible stainless steel bearing.
Cage materials: punch retainers material, using low carbon steel.
According to different purposes, also used brass, stainless steel plate.
Cutting system maintains a material, the use of high-intensity brass, carbon steel, and also the use of synthetic resin.
Crown cage: put the ball into the special when it is assembled with ball mouth can, in the case of low speed has a lower starting torque, flexible rotation.
Ribbon cage: a combination with and without paw paw, most of the 304 or 316 stainless steel materials, suitable for medium speed.
Phenolic cage: suitable for high speed, have the function of self lubricating, widely used in dental drill bearings.
