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 a slightly larger radius than that of the balls. They also have non-separable rings. Their straight forward basic design has many advantages:

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
