Deep groove ball bearings are among the most widely used type of bearing in the world. They can operate at high speeds and can carry radial and (limited) axial loads. They are commonly used in electric motors, compressors, fans, and conveyors.

Deep groove ball bearings are the most common type of ball bearing. They are commonly used in electric motors and in household appliances, car motors, office machinery, automation control, and garden and household tools. They have deep raceway grooves and their race dimensions are close to the dimensions of the balls that run inside.

They fall under two designs: there are single-row deep groove ball bearings with a single row ; and there are double-row bearings, which have two rows of bearing balls. They can also be made in different sizes and for different loads according to their application, from miniature ball bearings for light loads and small assemblies to large deep groove ball bearings and heavy load deep groove bearings.
