This double row deep groove ball bearing carries the designation 4302-BB-TVH, with a bore diameter of 15.0 mm, outside diameter of 42.0 mm, and width of 17.0 mm. Net mass is 0.115 kg. The bearing runs with a glass fibre reinforced plastic cage (TVH) and normal radial internal clearance (CN, Group N). Limiting speed is 17500 1/min, reference speed 11600 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 compared to a pressed steel cage. Normal internal clearance (CN) suits standard shaft and housing fits without preload requirements. The bearing is suitable for grease or oil lubrication, and the combination of double row geometry with a low-friction cage supports operation at the stated speed limits without additional sealing arrangements.
