Carries radial loads in a single row of balls running in deep grooves that accommodate a moderate amount of axial load in either direction. Bore diameter is 55.0 mm, outside diameter 100.0 mm, width 25.0 mm, net mass 0.717 kg, limiting speed 3900 1/min. The cage is a pressed steel sheet metal type (JN), radial internal clearance is CN (Group N), and both sides are fitted with seals (2RSR), so the bearing runs pre-lubricated and does not require external sealing arrangements. The seals on both sides retain grease and keep out dust and moisture, allowing operation without additional protective covers. Standard CN clearance suits general duty at the stated speed limit without preload issues, and the steel cage gives stable ball guidance across the full speed range listed. Dimensionally and constructionally interchangeable with SKF 62211-2RS1, NSK 62211DDU, and NTN 62211LLU.
