Additional Details
Double row deep groove ball bearings have a design and operation similar to two single row deep groove ball bearings. They are robust, require little maintenance, operate at high speeds, and support both radial and axial loads in both directions. They are slightly larger than single row bearings of the same bore and outer diameter but have a significantly higher load-carrying capacity.
