This double row deep groove ball bearing carries a 30.0 mm bore, 72.0 mm outside diameter and 27.0 mm width, with a net mass of 0.487 kg. It is fitted with a plastic cage (TVH) and radial internal clearance in group CN (Group N). Limiting speed is rated at 9400 1/min, with a reference speed of 7500 1/min. The double row design carries higher radial loads within the same envelope compared to a single row bearing, while the plastic TVH cage reduces friction and mass, supporting the stated speed ratings. Standard CN internal clearance makes it suitable for general-purpose mounting without special fits, and the open design requires the operator to provide appropriate lubrication and sealing arrangements according to the application's contamination and speed demands.
