DESCRIPTION

Heavy duty needle roller bearings consists of a machined and ground channel-shaped outer ring with a complement of needle rollers and a cage. The high-strength cage retains and guides the rollers. An optional lubrication groove and hole in the outer ring facilitates re-lubrication. These bearings can be used with or without machined and ground inner ring, depending on the suitability of the shaft as a raceway surface.
