1. Bearing material
Outer ring, inner ring, ball:
High-carbon chromium bearing steel Gcr15(JIS SUJ2,AISI 521000), or stainless steel 9Cr18(AISI 440C)
Cages:
Steel plates and nylon can be used in general situation, while rubber and stainless steel for special usage.
Cover:
Steel plate for shield, and rubber for seals
Rings and balls vacuum dealing with treatment of high carbon chromium bearing steel GCR15 is the standard material to produce the accurate internal and external circle and ball. This material is same with the USA AISL 52100, Germany DIN 100Cr6, Japan JISSUJ2.
The standard cage is made of carbon steel by cold, but in-corrosive environment, no parallel, or under high-speed operation, we can use stainless steel, nylon or phenolic resin cage according to customer’s request.
Main Production:
Deep Groove Ball Bearing / Angular Contact Ball Bearing/ Taper Roller Bearing/ Spherical Roller Bearing /Cylindrical Roller Bearing / Thrust Ball Bearing /Thrust Roller Bearing /Self-aligning ball bearing/Self-aligning roller bearing/Pillow Block Bearing /Needle Roller Bearing /Tracking Roller Bearing/ Auto Bearing Etc.
Production process:
1. Abrasive machining of steel pipe;
2. The inner & outer ring grinding;
3. The precision work of inner ring & outer ring
4. Bearing cleaning;
5. The Assembly of inner ring , outer ring , bearing balls &
cage, etc.
6. Bearing inspection( precison, noise & vibration levels).
