This deep groove ball bearing carries radial and moderate axial loads through a single row of balls running in a 90.0 mm bore, 160.0 mm outside diameter, 30.0 mm wide ring set. The cage is a sheet steel design (JN), mass is 2.21 kg, limiting speed reaches 6300.0 1/min and reference speed 5100.0 1/min. Radial internal clearance is set to C5 (Group 5), and the bore type is marked Z. The C5 clearance class gives extra internal play, which suits applications with heat generation or shaft fit conditions that would otherwise tighten the running clearance too much. The sheet steel cage keeps mass low and is suited for higher speed ranges within the stated limiting and reference speed values. No sealing or shielding is fitted, so lubrication and contamination protection must be provided externally. Equivalent bearings from other manufacturers: SKF 6218/C5, NSK 6218C5, NTN 6218C5.
