Carries axial loads in a single direction while keeping a compact axial section, using needle rollers arranged radially in a cage to support the axial washer. The AXW17 unit has a net mass of 11.54 g, a limiting speed of 12300 1/min and a reference speed of 5800 1/min. The needle roller bearing requires a shaft washer and housing washer to form a complete axial bearing arrangement, as it does not include integrated raceways. Its low axial height suits mounting positions where radial space for a full needle bearing set is limited, and the speed ratings indicate it can run at moderate to higher rotational speeds under axial load in one direction only.
