This needle roller bearing carries a single row of rollers without an inner ring, contained within a solid outer ring 28.0 mm in outside diameter and 13.0 mm wide. The design incorporates lip seals on both sides, designated 2RSR, protecting the rolling elements from contamination while retaining lubricant within the bearing. Net mass is 19.5 g, and the limiting speed reaches 12600.0 1/min with the standard cage. The sealing arrangement on both sides makes this bearing suitable for applications where protection against dust and moisture ingress is required without additional external sealing components. As the outer ring carries the rollers directly without an inner ring, shaft-mounting requires a hardened and ground shaft surface serving as the inner raceway. The standard cage guides the roller set circumferentially, maintaining roller spacing across the operating speed range up to the stated limiting speed.
