Description
Caged Needle Bearings possess an outer ring made from through-hardened bearing steel. The cage guides the needles and retains them in the outer ring. The bearings may be used without an inner ring if the shaft journal serving as a raceway is of sufficient hardness and has the correct surface finish.
NRB Industrial (NIBL) Needle Roller Bearing is designed for high static and dynamic load capacities and has the ability to withstand overloading, shocks, and vibration.
NRB manufactures Needle Roller Bearings with and without inner rings.

Features
- In applications where less space is available, needle roller bearings offer a very compact solution
- Despite their low cross-sectional height, they have a high load-carrying capacity
- The possibility of assembling inner and outer rings separately permits interference fits for shaft and housing and also enables easy maintenance
