Features of NAO20X35X17 Needle roller bearings with machined rings, with an inner ring

1.Low cross section
In applications where less space is available, needle roller bearings offer a very compact solution

2.High load carrying capacity
Despite their low cross sectional height, they have a high load carrying capacity.

3.Separable design
The possibility of assembling inner and outer rings separately permits interference fits for shaft and housing and also enables easy maintenance inspections.

4.High stiffness
Owing to their large number of small-diameter rollers, needle roller bearings with machined rings have high stiffness.
5.Accommodate axial displacement
Needle roller bearings with machined rings can accommodate axial displacement. When using raceways on the shaft, the displacement distance is not limited by the bearing.
