Single row angular contact ball bearings have single raceway grooves in the inner and outer rings that are relatively offset. These bearings can support axial loads in one direction only.

Single row deep groove ball bearings are available capped (with seals or shields) or open. Open bearings that are also available capped may have recesses in the ring side faces

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. They also have non-separable rings.
