Description

This needle roller bearing operates with a solid roller stud featuring a fixing thread and a mounting aid, combined with a particularly thick-walled outer ring. Outside diameter is 40.0 mm and net mass is 0.295 kg. Axial guidance of the outer ring is achieved through plastic axial plain washers, a contact flange, and a contact washer, without an eccentric collar. Sealing is provided in three stages by plastic axial plain washers (PP) on both sides, which keeps contamination out while the outer ring rotates against the roller stud. This configuration allows the outer ring to run directly on a track or guide surface, with the load transmitted through the needle roller and cage assembly to the solid stud.
