This needle roller bearing supports radial loads through a two-row needle roller set, running without an inner ring and without ribs on the outer race. The outside diameter is 35.0 mm, net mass is 54.39 g, the limiting speed reaches 18100 1/min, and the reference speed is 11000 1/min. The absence of an inner ring means the shaft seat must act as the running surface, requiring a hardened and ground shaft to match the bearing's raceway. The two-row needle arrangement gives increased radial rigidity in a compact cross-section, and the lack of ribs on the outer ring means axial guidance of the needle rollers must be provided by the housing or adjacent components. No seals are fitted, so lubrication and contamination protection must be arranged externally through the housing design.
