Deep groove ball bearings (GB/T 276-2003), formerly known as single row radial ball bearings, are a widely used type of 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 of radial and axial forces. It can also be used on components that can withstand axial loads, such as low-power electric motors, car and tractor gearboxes, machine tool gearboxes, general machines, tools, etc
