Description

This needle roller bearing guides the outer ring along a fixed track through a solid roller stud with fixing thread and a mounting aid, simplifying installation without additional fasteners. The outer ring is particularly thick-walled and carries a full complement needle roller set, giving a compact single-row design without a cage. Axial guidance of the outer ring is achieved through plastic axial plain washers, a contact flange and a contact washer, with three-stage PP sealing on both sides. Outside diameter is 72.0 mm, width 80.0 mm, net mass 0.999 kg, and the design has no eccentric collar. The full complement roller set supports the outer ring surface fully, suited for applications where the track needs continuous radial support rather than intermittent contact. The PP sealing on both sides limits ingress of contaminants along the shaft, while the plastic axial plain washers maintain consistent axial positioning of the outer ring during operation. Since there is no eccentric collar, the track geometry is fixed and does not allow for adjustment once mounted.
