4304ATN9 SKF Double Row Ball Bearing
SKF Double Row deep groove ball bearings are similar in design to single row deep groove ball bearings. They have two parallel deep grooves and high conformity between the balls and raceways. They are very suitable for bearing arrangements where the load carrying capacity of a single row bearing is inadequate for the same bore and outside diameter. Double Row ball bearings are slightly wider than single row ball bearings, but have a considerably higher load carrying capacity.
