This needle roller bearing is a stud type track roller with a particularly thick-walled outer ring and a full complement needle roller set, giving high load capacity within a compact outside diameter of 19.0 mm. The unit is built on a solid roller stud with fixing thread and a mounting aid, with an outside diameter of 19.0 mm, a width of 32.0 mm and a net mass of 0.031 kg. Axial guidance of the outer ring is provided by plastic axial plain washers together with a contact flange and contact washer, and the design includes an eccentric collar for stroke adjustment. Sealing is three-stage, formed by plastic axial plain washers (PP) on both sides, keeping contaminants away from the needle roller set and retaining grease inside the bearing. The fixing thread and mounting aid allow direct stud mounting without a separate housing, while the thick-walled outer ring and full complement roller set make the bearing suited for rolling and guiding applications where the outer ring surface itself acts as the running track.
