Machined Type Needle Roller Bearing Heavy Duty (NKJS)

About Heavy-Duty Needle Roller Bearings

Heavy-duty needle roller bearings consist of a machined and ground channel-shaped outer ring with a complement of needle rollers, and a cage.
The high-strength cage retains and guides the rollers. An optional lubrication groove and hole in the outer ring facilitates re-lubrication.
These bearings can be used with or without a machined and ground inner ring, depending on the suitability of the shaft as a raceway surface.

Features

A thick outer ring provides maximum load capacity and shock resistance with a relatively small radial cross-section.
