This needle roller bearing has a drawn cup outer ring with open ends, according to DIN 618, carrying the designation HK3018-RS-L271. The outside diameter is 37.0 mm, width 18.0 mm, and net mass 34.01 g. A lip seal is fitted on one side (RS), while the other end remains open. The limiting speed is 5200 1/min. The drawn cup design gives a thin-walled outer ring, allowing a compact radial section where installation space is limited. The lip seal on one side retains grease and restricts contamination ingress from that end, while the open end permits axial fitting against a shoulder or shaft feature. As with drawn cup needle roller bearings of this type, the design accommodates full complement needle rollers for radial load carrying capacity within the stated speed limit, and the open end requires the shaft or housing arrangement to provide axial location and sealing as needed on that side.
