Description
Radial load capacity in a compact cross-section comes from a full complement of needle rollers guided by a standard cage, giving this needle roller bearing an outside diameter of 37.0 mm and a net mass of 51.77 g. The limiting speed reaches 15800 1/min, with a reference speed of 9300 1/min under the manufacturer's test conditions. The light series design keeps radial dimensions small while maintaining rolling contact along the full roller length, making the bearing suitable where shaft space is limited but radial load support is required. As this is a bearing without an inner ring, it must run directly on a hardened and ground shaft seat, and lubrication together with sealing has to be provided by the surrounding housing design.
