Needle Roller Bearings

Heavy Duty Needle Rollers

When the application requires high static, dynamic or shock loads heavy duty needle rollers are ideal. Machined or Heavy Duty Type needle rollers are bearings with a relatively low sectional height and a solid machined outer ring. The solid outer ring provides high rigidity and allows this bearing to handle larger loads than drawn cup needle bearings. A lubrication groove and hole in the O.D. facilitates relubrication through the outer ring. A caged type or full complement type are options, therefore making it possible to select a suitable bearing for use under various conditions. Inner rings can be used for applications where it is impractical to use the shaft as the inner raceway.
