Description

This needle roller bearing guides an outer ring along a track through a solid roller stud with fixing thread and a mounting aid, allowing direct mounting into a bore without a separate axle. The outer ring has a particularly thick wall and carries a full complement needle roller set, giving high load capacity for its outside diameter of 19.0 mm and width of 32.0 mm. Axial guidance of the outer ring is achieved through plastic axial plain washers together with a contact flange and contact washer. Net mass is 28.754 g. The design has no eccentric collar. Sealing is provided in three stages by plastic axial plain washers (PP) on both sides, restricting contact and reducing wear while keeping contaminants away from the needle roller set. Because the roller stud is solid and threaded, mounting is straightforward and the bearing runs directly on the track surface without an additional axle component. The full complement roller set increases radial load capacity compared to a caged design, at the expense of somewhat higher friction, which should be accounted for when selecting the operating speed.
