This double row deep groove ball bearing carries the design code 4200-BB-TVH, with a bore of 10.0 mm, outside diameter of 30.0 mm and width of 14.0 mm. The cage is made of plastic (TVH design), and the bearing weighs 0.05 kg. Limiting speed is rated at 25500 1/min, with a reference speed of 21600 1/min, and radial internal clearance falls in the CN (Group N) range. The double row arrangement allows the bearing to accommodate radial loads along with axial loads acting in both directions, providing higher rigidity in a compact width compared to a single row design. The plastic cage reduces friction losses and supports the stated speed ratings, while the CN clearance corresponds to standard operating conditions without preload. As supplied without integrated sealing, the bearing requires external protection of the raceways and grease or oil lubrication appropriate to the operating speed and environment.
