This needle roller bearing has a drawn cup design with open ends, built to DIN 618. Outside diameter is 28.0 mm, width is 18.0 mm, and net mass is 22.24 g. A lip seal is fitted on one side, marked RS in the symbol, while the other end remains open. The limiting speed is rated at 7000 1/min. The thin-walled drawn cup construction keeps radial space requirements low while accommodating a full complement of needle rollers for load-carrying capacity. The one-sided lip seal restricts contamination ingress and retains lubricant on the sealed face, while the open end allows axial lubrication access during service. As an open-end version, the bearing requires a shaft that serves as the inner raceway surface, and axial location must be provided by the surrounding construction.
