This needle roller bearing carries a solid inner ring and an outer ring with two ribs, forming a single-row full complement of needle rollers between the raceways. Bore diameter is 30.0 mm, outside diameter 47.0 mm, and width 17.0 mm, giving a compact radial cross-section for the given envelope. The bearing weighs 103.25 g and runs with a standard cage. Limiting speed is rated at 12600 1/min, with a reference speed of 6600 1/min. The two-rib outer ring locates the needle roller set axially, allowing the bearing to take radial loads within a defined housing bore without a separate retaining shoulder. The solid inner ring provides a hardened raceway suited to direct shaft mounting where axial ring displacement must be avoided. With a standard cage, the roller set is guided for even load distribution across the roller length, matching the stated speed ratings at the specified bore and outside diameter.
