Deep groove ball bearing (GB/T 276-2003), formerly known as single row radial ball bearing, is a widely used rolling bearing. Its characteristics are low frictional resistance, high rotational speed, and can be used on components that can withstand radial loads or combined loads acting both radially and axially. It can also be used on components that can withstand axial loads, such as low-power electric motors, automotive and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.

Deep groove ball bearings can be used in gearboxes, instruments and meters, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, engineering machinery, roller skates, yoyo balls, etc.
