NK Series

Description

NK Series Machined Needle Roller Bearings are precision-engineered radial bearings with a machined steel outer ring, needle roller and cage assembly, and no inner ring. They are designed for applications where the shaft itself acts as the raceway and has been hardened and precision-ground. Their compact design provides high load capacity while minimizing installation space.

Features

Machined, high-strength steel outer ring
High radial load-carrying capacity
Compact design with low radial cross-section
Suitable for high-speed applications
Low friction and smooth operation
High rigidity and long service life
Available in open designs with lubrication grooves/holes on larger sizes
Requires a hardened and ground shaft because the bearing is supplied without an inner ring.
