This needle roller bearing is designed as a stud type track roller with a solid roller stud, fixing thread and mounting aid for direct installation. The outer ring is particularly thick-walled and carries a needle roller and cage assembly, giving an outside diameter of 40.0 mm and a width of 58.0 mm at a net mass of 248.7 g. Axial guidance of the outer ring is provided by plastic axial plain washers together with the contact flange and contact washer, and the stud incorporates an eccentric collar. Sealing is arranged in three stages using plastic axial plain washers on both sides, marked PP, which keeps contaminants away from the needle roller set while the outer ring rotates on the stationary stud. The eccentric collar allows adjustment of the roller position, and the thick-walled outer ring combined with the solid stud design suits applications where the roller runs directly on a track surface under radial load.
