This axial bearing washer supports thrust bearing arrangements by providing a hardened raceway surface for the needle rollers or cage assembly to run against. Manufactured to DIN 5405-3/ISO 303, the AS1730 has a net mass of 3.5 g, matching the compact dimensional standard defined for this washer type. The washer is designed to be paired with AXK and K811 series thrust needle roller bearings, forming a complete axial bearing arrangement when combined with the appropriate cage and roller assembly. As a separate raceway component, it allows the bearing arrangement to accommodate axial loads while keeping the overall installation flat and space-saving, with no integrated sealing or lubrication provisions of its own, since these are handled at assembly level with the mating bearing components.
