Double-row deep groove ball bearings are particularly suitable for bearing arrangements where the load-carrying capacity of single-row deep groove ball bearings is insufficient. For double-row deep groove ball bearings with the same outer and inner diameters as single-row deep groove ball bearings, they have a larger width and significantly higher load-carrying capacity than single-row deep groove ball bearings in the 62 and 63 series. Double-row deep groove ball bearings are available in only one design: open (without seals or dust caps).
