This needle roller bearing has a drawn cup design with open ends, built to DIN 618, carrying the designation HK2018-RS-L271. The outside diameter measures 26.0 mm, width is 18.0 mm, and net mass is 21.14 g. A lip seal is fitted on one side (RS), while the limiting speed reaches 7600 1/min. The open-end construction allows shafts to pass through both sides, simplifying mounting where axial positioning is handled elsewhere in the assembly. The single-side lip seal keeps contamination out on the sealed face while permitting lubricant access from the open side, so grease replenishment remains straightforward during service. The thin-walled drawn cup keeps radial space requirements low while the full complement of needle rollers provides load capacity within a compact envelope, matching the specified outside diameter and width.
