Machined Type Needle Roller Bearing

NK Metric Needle Roller Bearing has a one-piece, channel-shaped outer ring of bearing -quality steel heat treated to yield maximum load rating. The integral end flanges provide axial location for the needle rollers. The bore of the end flanges serves as piloting surfaces for the cage.
A steel cage provides inward retention for the needle rollers, and the design assures roller stability and minimizes friction between the cage and the needle rollers. The cage has maximum strength consistent with the inherent high-load ratings of needle roller bearings.
