Deep groove ball bearing formerly known as single row centripetal ball bearing, is the most widely used kind of rolling bearing. Its characteristics are small friction resistance, high speed, can be used to bear radial load or radial and axial combined load on the parts, can also be used to bear axial load on the parts, When it only bears radial load, the contact Angle is zero.

When deep groove ball bearings have large radial clearance, they have the performance of angular contact bearings and can withstand large axial loads. The friction coefficient of deep groove ball bearings is very small, and the ultimate speed is also very high.
