This needle roller bearing guides an outer ring designed as a track roller, with bore diameter 35.0 mm and outside diameter 72.0 mm. It is built as a single row full complement needle roller bearing with a particularly thick-walled outer ring and an inner ring, giving it net mass of 0.636 kg. Axial guidance of the outer ring is achieved through plastic axial plain washers combined with contact washers, and sealing is provided in three stages by plastic axial plain washers (PP) on both sides. The full complement needle roller set gives high radial load carrying capacity within a compact cross-section, while the thick-walled outer ring allows direct rolling contact on a track surface without an additional housing. The three-stage PP sealing arrangement keeps contaminants away from the raceway and retains lubricant, making the bearing suitable for continuous rolling motion where axial guidance of the outer ring and low-maintenance operation are required.
