This needle roller bearing carries a particularly thick-walled outer ring paired with a needle roller and cage assembly, mounted on a solid roller stud that has a fixing thread and a mounting aid. The outer ring outside diameter is 30.0 mm and the overall width is 40.0 mm, with a net mass of 89.5 g. Axial guidance of the outer ring is achieved through plastic axial plain washers together with the contact flange and contact washer, and the design includes an eccentric collar for adjustment of the track roller position. Sealing is provided in three stages by plastic axial plain washers (PP) on both sides, which keeps contamination away from the raceway and rolling elements. This arrangement suits applications where the track roller must run against a guide surface with reliable axial location and where the eccentric collar allows fine adjustment of clearance or preload during installation.
