This needle roller bearing is a yoke type track roller featuring a particularly thick-walled outer ring, a needle roller and cage assembly, and an inner ring. Bore diameter is 10.0 mm, outside diameter 30.0 mm, net mass 59.911 g. Axial guidance of the outer ring is provided by plastic axial plain washers together with contact washers, and the sealing type is PP. Three-stage sealing, formed by plastic axial plain washers on both sides, restricts contamination ingress while the roller runs directly on a track or cam surface. The thick-walled outer ring gives the assembly the section strength needed to act as the running surface itself, with axial location built into the bearing rather than relying on separate retaining parts.
