Key Features
- Supports heavy radial loads
- Low friction roller design allows for high speed applications
- Separable components simplify mounting and removal
- Design has two ribs on the outer ring and one rib on the inner ring, making type NJ bearings well suited for use as semi-locating bearings
- Enhanced operational reliability
- Long service life
