This axial bearing washer serves as a flat locating surface for axial needle roller bearings, providing a hardened running track for the rolling elements. Manufactured to DIN 5405-3/ISO 303, it is designed to work together with AXK and K811 series bearings, with a net mass of 83.4 g. The washer has no integral flanging ring, which means axial and radial positioning of the assembly must be ensured by the surrounding housing or shaft design. Its flat geometry allows it to accommodate the axial load transmitted through the needle roller set while maintaining a compact axial installation height, matching the corresponding AXK or K811 bearing it is paired with.
