This needle roller bearing operates as a stud type track roller with a single row of needle rollers and a particularly thick-walled outer ring, giving it high load-carrying capacity within a compact outside diameter of 52.0 mm. The design integrates a needle roller and cage assembly mounted on a solid roller stud fitted with a fixing thread and a mounting aid, simplifying installation without additional fasteners. Axial guidance of the outer ring is achieved through plastic axial plain washers together with a contact flange and contact washer, and net mass is 443.0 g. Sealing is provided in three stages by plastic axial plain washers (PP) on both sides, protecting the needle roller set from contamination while maintaining smooth rolling contact. As the bearing has no eccentric collar, it is intended for straightforward track roller applications where guided axial positioning of the outer ring is required rather than eccentric adjustment, making it suited for use on cam tracks and guide rails needing stable rolling motion.
