Needle roller bearing NKI40/30-TV-XL is a solid-ring design with a full complement of needle rollers, giving a compact radial section for the 40.0 mm bore, 55.0 mm outside diameter and 30.0 mm width. Net mass is 0.206 kg. The bearing is rated for a limiting speed of 10200 1/min and a reference speed of 5400 1/min, with radial internal clearance in group CN (Group N) and a TV cage. The CN clearance keeps radial play within the standard range, suited to shaft and housing fits that do not require reduced or increased clearance. The TV cage guides the needle rollers and limits skewing, supporting the stated speed ratings under pure radial load. As an open bearing it requires external sealing and a separate lubrication supply matched to the specified limiting and reference speeds.
