KOYO NRB — KOYO NRB HJ-445628
- One-piece channel-shaped outer ring of bearing quality steel, heat-treated to provide maximum load rating
- Integral end flanges provide axial location for the needle rollers
- Bores of the end flanges serve as piloting surfaces for the cage, locating it to prevent removal of the lubricant film on the raceway
- These bearings have a steel cage which provides inward retention for the needle rollers
- The design assures roller stability and minimizes friction between the cage and the needle rollers
