Deep groove, or single row radial, ball bearings are the most widely used bearings. They utilize an uninterrupted raceway that makes them optimal for radial loads .This design permits precision tolerance, even at high-speed operation.Ball Bearing Description Deep groove bearings have race dimensions that are similar to their ball dimensions. These bearings can be used in a wide variety of applications. They have grooved raceways on the inner and outer rings allowing them to sustain moderate radial and axial loads in both directions.

Single Row Deep Groove. Single row deep groove ball bearings are the most widely used roller bearing type in the world due to their versatility and overall performance. They are characterized by having deep raceway grooves in which the inner and outer rings have circular arcs of slightly larger radius than that of the balls.
