This deep groove ball bearing supports radial loads and moderate axial loads through a single row of balls riding in a deep raceway groove. The bore diameter is 55.0 mm, outside diameter 100.0 mm, and width 21.0 mm. It uses a steel sheet metal cage (JN) and is sealed on both sides (RSR), which keeps contamination out and retained grease in. The limiting speed is 3900 1/min, and net mass is 0.595 kg. Radial internal clearance falls in group CN (normal clearance). The integrated seals make this bearing suitable for positions where relubrication access is limited, since grease is factory-filled and retained within the sealed cavity. Normal internal clearance (CN) covers standard fit conditions without added preload. Dimensionally and constructionally interchangeable with SKF 6211-RS1, NSK 6211DU, and NTN 6211LU.
