Needle Roller Bearing has high load capacity and can run on high speed. It has space-saving design and is suitable for limited radial dimension. The structure can be with or without an inner ring.
The needle bearing industry in China is not healthy, fierce competition has lead to big variation on quality, even average quality has been submerged in low quality products. Every factory do know how to make their bearing better from a little to a lot!
For many needle bearing series, RLM provide additional quality upgrading choices to make the bearing more close to premier brands quality, eg. comparing to INA/IKO original.
- Ring Material: Xincheng steel (SKF supplier)
- Cage material: Bao steel(Big factory, Chinese premier level steel factory)
- Outer ring: Superfinishing
- Raceway: Precision grinding + Superfinishing
- Flange: Lip precision turnning (After heat treatment)
- Needle: G2 needle, using 2µ section instead of 3µ section (Needles 5~6 times grinding, then superfinishing)
- Roundness run out controlled within 1µ
Each quality upgrading may lead to cost increase, RLM keeps working on this quality upgrading for customers who really cares about quality and aim about long time business.
