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. Their straight forward basic design has many advantanges:Excellent for high speeds，Good radial load capacity，Acceptable axial load capacity in both directions，Have low torque capacity at startup and running speeds，Can operate with low noise，Require little maintenance

As flexible as the performance is, the configurations of single row ball bearnigs is also as versatile. These bearings often have steel shields or rubber seals installed on one or both sides and are pre-lubricated with grease.
