This double row deep groove ball bearing carries the design 4304-BB-TVH, with a bore of 20.0 mm, outside diameter of 52.0 mm and width of 21.0 mm. The bearing weighs 0.212 kg and uses a TVH cage made of plastic, which reduces friction and mass compared to a solid metal cage. Limiting speed is rated at 13100 1/min, with a reference speed of 9300 1/min, and radial internal clearance falls within the CN (Group N) range. The double row arrangement increases radial load capacity within the same envelope dimensions as a single row design, while the plastic TVH cage supports smooth ball guidance at the stated speed ratings. Standard CN clearance suits general mounting conditions without preload adjustments, making this bearing suitable where two rows of balls are needed to handle combined radial loading at moderate to high rotational speeds.
