Carries radial loads with a single row of balls running in deep grooves, providing additional axial guidance in both directions. The bearing has a bore diameter of 90.0 mm, outside diameter of 160.0 mm, and width of 30.0 mm, with a net mass of 2.189 kg. It uses a steel sheet metal cage (JN), and radial internal clearance is CN (Group N), the normal group. Limiting speed is rated at 6300.0 1/min, with a reference speed of 5100.0 1/min. This design suits applications requiring stable radial and moderate axial support under normal running clearance, without built-in sealing, so external sealing and a separate lubrication supply must be provided by the surrounding assembly. The steel sheet metal cage keeps mass low while maintaining ball guidance at the stated speed ratings. Dimensionally and constructionally interchangeable with SKF 6218, NSK 6218, and NTN 6218.
