This needle roller bearing works as a stud type track roller with a particularly thick-walled outer ring and a full complement needle roller set, giving load capacity in a compact envelope of 22.0 mm outside diameter and 36.0 mm width, with a mass of 41.947 g. The solid roller stud has a fixing thread and a mounting aid, and axial guidance of the outer ring is provided by plastic axial plain washers together with a contact flange and contact washer, with no eccentric collar. Sealing is achieved in three stages by plastic axial plain washers (PP) on both sides, keeping contamination away from the raceway while the outer ring runs directly against the track surface. The stud design with fixing thread allows direct mounting without a separate housing, and the arrangement suits applications where a track roller must run under load with integrated axial guidance and sealing built into the outer ring assembly.
