Single-row deep groove bearings are the most common type of rolling bearings. Their use is widespread. The raceway grooves on both the inner and outer rings have circular arcs of slightly larger radius than that of the balls.
The Inch system series deep groove ball bearings that we designs and manufactures, go from 3.175 mm bore up to 66.675 mm external diameter.
