This needle roller bearing guides a yoke type track roller with a particularly thick-walled outer ring running on a needle roller and cage assembly and an inner ring. Bore diameter is 17.0 mm, outside diameter 40.0 mm, and net mass 0.137 kg. Axial guidance of the outer ring is achieved through plastic axial plain washers and contact washers, which locate the outer ring against the inner ring. Sealing is provided by plastic axial plain washers (PP) on both sides, giving three-stage protection against contamination without added rolling resistance. The design suits applications where a cam roller runs directly on the outer ring surface and where axial location must be maintained without separate retaining elements, while the compact cross-section and integral sealing keep maintenance and lubricant retention requirements low.
