Deep groove ball bearings are particularly versatile. They have low friction and are optimized for low noise and low vibration which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.
Single row deep groove ball bearings are the most widely used bearing type. They are available capped (with seals or shields) or open. Open bearings that are also available capped may have recesses in the ring side faces .
