This needle roller bearing carries a full complement of needle rollers guided directly against the housing bore, giving a radial section that keeps the outside diameter at 32.0 mm while net mass stays low at 0.041 kg. It uses a standard cage, and the design allows a limiting speed of 18500 1/min with a reference speed of 10700 1/min. The absence of an inner ring means the shaft seat itself must act as the running surface, so the shaft has to be hardened and ground to the required tolerance before mounting. Radial space is used efficiently thanks to the thin-walled needle roller set, and the standard cage keeps the rollers evenly spaced for stable rotation across the stated speed range.
