This washer serves as the housing locating element for axial cylindrical roller bearing sets of the 874 series, used together with K874 and WS components. Outside diameter is 52.0 mm and net mass is 41.9 g, matching the flat raceway geometry required for axial load transfer in this bearing arrangement. The flat, ground surface provides the running track for the axial cylindrical roller bearing and must be paired with the corresponding K874 roller and cage assembly and WS washer to form a complete axial support unit. Correct axial alignment during mounting is required, as the locating washer carries the reaction load transmitted through the rollers and has no self-aligning capability of its own.
