Bearing is miniature bearing industry one of the biggest manufacturer in the world, and her high precision products are widely used in video recorder, air conditioner, vacuum cleaners, auto motors.
Medical machinery and computer peripheral hardware driver, etc, especially in high speed and high precision products, especially in the industry leading position.
Of the bearing company, founded in 1951, is located in nagano, Japan.
The business scope of the group company has bearings, electronics, machinery parts, machine parts and special parts, etc.
Its leading products is the micro, small bearings, small precision motors, fan motor bearing and so on more than 2000 kinds of varieties, is the world's largest miniature and small bearing production enterprises.
Materials used in 1)
Ring, rolling body materials required by the performance: rolling fatigue strength, high hardness, high wear resistance, 2)
Cage materials required by the performance: good dimensional stability, mechanical strength and good workability.
According to different purposes and demands of its, impact resistance, heat resistance, good corrosion resistance.
3)
Ring and rolling body material: ring and rolling body usually use high carbon chromium bearing steel.
Most of the bearing, using JIS SUJ2 steel grade.
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.
4)
Cage materials: stamping materials, use of 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.
1) performance
Low noise;
2)
High speed;
3)
High precision;
4)
Long life.
