Description

This needle roller bearing carries a particularly thick-walled outer ring running on a needle roller and cage assembly, mounted on a solid roller stud with fixing thread and a mounting aid, featuring an eccentric collar for adjustment during installation. Outside diameter is 52.0 mm, width 66.0 mm, and mass netto 0.49 kg. Axial guidance of the outer ring is achieved through plastic axial plain washers together with a contact flange and contact washer, giving defined axial positioning without additional bearing components. Sealing type PP provides three-stage sealing by plastic axial plain washers on both sides, restricting contaminant ingress from the running surface. The design suits applications where a stud-mounted track roller must run directly on a guide surface with fixed axial location, and where the eccentric collar allows fine positioning adjustment during assembly without modifying the mounting structure.
