About Heavy-Duty Needle Roller Bearings

• Heavy-duty needle roller bearings consist 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 a machined and ground inner ring, depending on the suitability of the shaft as a raceway surface.
