Double Row
Double row deep groove ball bearings are very suitable for bearing arrangements where the load carrying capacity of a single row bearing is inadequate. The design of double row deep groove ball bearings is basically the same as that of single row deep groove ball bearings. The deep groove ball shaft-shaped raceway plus the excellent tightness between the raceway and the steel ball.For the same bore and outside diameter, double row bearings are slightly wider than single row bearings in the 62xx and 63xx series, but have a considerably higher load carrying capacity.
Double row deep groove ball bearings are only available as open bearings (without seals or shields).
