This locating washer forms the housing-side raceway of an axial cylindrical roller bearing set of the 811 series, used together with matching cage and shaft washers such as K811 and WS. GS81106 has an outside diameter of 47.0 mm and a net mass of 19.9 g, machined as a flat ring providing a hardened running surface for the roller and cage assembly. The single-direction design allows the washer to carry axial load in one direction only, requiring correct orientation against the shaft washer during assembly. As a separate raceway component, it must be paired with the corresponding cage and shaft washer of the same size to form a complete axial cylindrical roller bearing, and it does not include integrated sealing or lubrication, so lubrication must be applied according to the assembly requirements of the full bearing set.
