Deep groove ball bearing is the most widely used rolling bearing. It is characterized by low friction resistance and high speed. It can be used for parts bearing radial load or combined load of radial and axial at the same time. It can also be used for parts bearing axial load, such as small power motor, automobile and tractor gearbox, machine tool gearbox, general machines, tools, etc.
Deep groove ball bearings mainly bear radial load, and 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 large radial clearance, it has the performance of angular contact bearing and can bear large axial load. The friction coefficient of deep groove ball bearing is very small and the limit speed is also very high.
