This needle roller bearing is designed with a drawn cup, open on both ends, and carries needle rollers running directly on a shaft as the inner running surface. The outside diameter is 10.0 mm, width 9.0 mm, and net mass 2.315 g. The limiting speed is 36500 1/min, with a reference speed of 30500 1/min, and the bearing is supplied without sealing. The open-end design allows the bearing to be mounted from either side and requires a hardened and ground shaft to serve as the inner race, keeping radial section height low for compact housing arrangements. As the bearing has no integrated sealing, lubricant retention and contamination protection must be provided externally through the housing design, and relubrication intervals should be planned according to the operating speed range indicated.
