This needle roller bearing is built as a drawn cup with an open end design according to DIN 618, featuring a lip seal on one side (RS). The outside diameter is 21.0 mm, width 18.0 mm, and net mass is 15.62 g. Limiting speed is rated at 9900 1/min. The single-side lip seal restricts contamination ingress from that direction while the open end allows shaft-side access, which should be accounted for during mounting orientation. The drawn cup construction keeps radial section low relative to load capacity, and the open-end design permits the bearing to be paired with an inner ring or run directly on a hardened shaft, depending on the assembly requirements.
