Deep groove ball bearing (GB/T 276-2003), formerly known as single row radial ball bearing, is the most widely used kind of rolling bearing. It is characterized by low friction resistance, high speed, can be used to bear radial load or radial and axial combined load of the machine parts, can also be used to bear axial load on the machine parts, such as low-power motor, automobile and tractor gearbox, machine tool gear box, general machines, tools, etc
Deep groove ball bearings mainly bear radial load, can also bear radial load and axial load at the same time. When it only bears radial load, the contact Angle is zero. When the deep groove ball bearing has a large radial clearance, it has the performance of angular contact bearing and can bear a large axial load. The friction coefficient of the deep groove ball bearing is very small, and the limit speed is also very high.
