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.
