1.Needle roller contour surface close at the end a little shrinkage.

2.Needle and the raceway line contact correction can be the result of the needle roller bearingTo avoid damaging the edge stress.

3. Bearing needle roller bearing is a thick wall of the outer ring, by the high temperature and high nitrogen quenching, high precision separation roller guided by high rigid outer rim, using linear contact roller can easily turn on the rolling path directly, and can bear big load.

4.To get rid of stress, supporting roller outer cambered surface design, curve roller with single or double seal, without sealing ring, sealing ring, etc. Various kinds of specifications.

classification
1. Radial needle roller and cage assemblies
2 na, NKI type needle roller bearings
3. RNA, NK model without inner ring needle roller bearings
4 hk drawn cup needle roller bearings
5. Type BK stamping outer ring needle roller bearing

Matters needing attention
1.Needle roller bearing capacity big, applicable to the limited size of installation of supporting structure,
2.Journal as rolling surface hardening on the surface, bearing use force fit into the hole, not for axial positioning.
Bearings should be injected into the right amount of grease before installation, under normal circumstances.
