Deep groove, or single row radial, ball bearings are the most widely used bearings. They utilize an uninterrupted raceway that makes them optimal for radial loads .This design permits  ball bearings use standard cages of pressed steel, as well as machined, brass cages for high-speed applications. NTN also offers bearings with locating snap rings.

Deep groove ball bearings come in many sizes, materials and varieties according to consumer needs, including special industrial uses such as high-temperature applications. High-temperature bearings are made to withstand temperatures up to 350°C (660°F) and are suitable for machines used in the metals industry or for industrial ovens.

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.
