This needle roller bearing operates as a stud type track roller, with an outside diameter of 52.0 mm, a width of 66.0 mm and a net mass of 0.448 kg. The outer ring is particularly thick-walled and houses a full complement needle roller set, running on a solid roller stud fitted with a fixing thread and a mounting aid. Axial guidance of the outer ring is achieved through plastic axial plain washers together with a contact flange and contact washer, without an eccentric collar. Sealing is provided by plastic axial plain washers on both sides, forming a three-stage seal that keeps contaminants out of the running track while retaining grease inside the bearing. The solid stud with fixing thread allows direct mounting without a separate housing, and the thick-walled outer ring together with the full complement roller set gives the bearing a load-bearing running surface suited to guiding and supporting loads along a track.
