This double row deep groove ball bearing, type 4211-B-TVH, has a bore diameter of 55.0 mm, an outside diameter of 100.0 mm and a width of 25.0 mm, with a net mass of 0.813 kg. The cage is made of plastic (TVH design), and the bearing runs with radial internal clearance CN (Group N). Limiting speed is rated at 6700 1/min, with a reference speed of 5900 1/min. The double row design increases radial load carrying capacity compared to a single row bearing of the same envelope dimensions, while the plastic cage reduces friction and mass, supporting the stated speed ratings. The CN clearance corresponds to normal operating clearance, suitable for standard fit conditions without preload. As this design has no integrated seals, external sealing and a separate lubrication supply must be provided according to the operating conditions and relubrication interval required.
