This needle roller bearing carries a full complement of needle rollers guided directly on a solid inner ring, giving a high radial load capacity within a compact cross-section. Bore diameter is 35.0 mm, outside diameter 50.0 mm, width 30.0 mm, and the net mass is 191.122 g. The limiting speed is 11400 1/min, with a reference speed of 6200 1/min, and radial internal clearance falls into the CN (Group N) group. The solid inner ring construction allows accurate shaft location and supports high radial stiffness where axial space is limited, consistent with the light NKI series design. The standard cage keeps roller spacing uniform under normal operating conditions, while the CN internal clearance provides the typical running clearance for general mounting arrangements without preload. As an open bearing, it requires external sealing and a separate lubrication supply appropriate to the operating speed and load.
