This seating washer transfers axial load between the shaft or housing face and the adjacent rolling bearing, providing a flat, defined bearing seat for the assembly. The component, designated U207, has a net mass of 0.056 kg, matching the compact dimensional range typical of the U2 washer series. Its flat construction allows it to be fitted directly against the bearing face without additional machining of the seat, simplifying axial location within the assembly. As a passive support element, it carries no independent load rating or speed limit of its own, and its performance depends entirely on the bearing and shaft arrangement it is paired with.
