This needle roller bearing guides a shaft through a particularly thick-walled outer ring, running on a needle roller and cage assembly seated on an inner ring, with a bore diameter of 12.0 mm and an outside diameter of 32.0 mm, weighing 0.064 kg. Axial guidance of the outer ring is provided by plastic axial plain washers and contact washers, giving the unit its yoke type track roller design. Sealing is achieved in three stages through plastic axial plain washers fitted on both sides (PP), keeping contaminants out of the raceway and retaining grease inside the bearing without extra maintenance. The thick-walled outer ring allows the roller to run directly on a track or cam surface, while the built-in axial guidance eliminates the need for separate thrust washers on the mounting side.
