This needle roller bearing guides a load along a track through a particularly thick-walled outer ring combined with a full complement needle roller set and an inner ring. Bore diameter is 25.0 mm, outside diameter 52.0 mm, and net mass 275.0 g. Axial guidance of the outer ring is provided by plastic axial plain washers together with contact washers, which also form a three-stage sealing arrangement on both sides, marked PP. The full complement roller set gives high radial load capacity within the bore and outside diameter stated, while the inner ring allows shaft mounting without a separate track pin. The plastic axial plain washers reduce friction at the guiding faces and keep contamination away from the roller set, which supports operation where the outer ring runs directly as a track roller under continuous rotation. The three-stage sealing on both sides retains grease within the bearing and limits the ingress of particles from the running surface it contacts.
