This deep groove ball bearing carries radial and moderate axial loads in a single row, with a bore diameter of 50.0 mm, outside diameter of 110.0 mm and width of 27.0 mm. It is fitted with shields on both sides (2Z) and a steel sheet metal cage (JN), giving a net mass of 1.08 kg. The limiting speed is 8000 1/min and the reference speed reaches 8400 1/min. The radial internal clearance is C3, wider than standard, which compensates for thermal expansion and interference fit at the mounting stage, keeping the bearing free of excessive preload during operation. The steel shields protect the raceway and balls from dust ingress while retaining the internal grease fill, so no external sealing arrangement is required. The steel sheet metal cage guides the balls at the stated speed range and suits mounting positions where a shielded, factory-lubricated bearing of Generation C design is needed.
