Deep groove ball bearings are versatile, self-retaining bearings with solid outer rings, inner rings and ball and cage assemblies. These products are of simple design, durable in operation and easy to maintain; they are available in single and double row designs and and in open and sealed variants. Due to the production technology used, open bearings can still have turned recesses on the outer ring for seals or shields.

Due to their low frictional torque, they are suitable for high speeds.
