Deep Groove ball bearing

Deep groove ball bearing, originally listed as centripetal ball bearing, is one of the most widely used rolling bearings. Its characteristics are small friction resistance and high speed. It can be used on the parts bearing both radial load and radial and axial load. It can also be used on the parts bearing axial load, such as low-power motors, automobile and tractor gearboxes, machine tool gearboxes, general machines and tools.

Working principle

Deep groove ball bearings mainly bear radial load, but also can bear both radial load and axial load. When it only bears radial load, the contact angle is zero. When deep groove ball bearings have large radial clearance, they have angular contact bearing performance, can withstand large axial loads, the friction coefficient of deep groove ball bearings is very small, and the ultimate speed is also high.

Bearing characteristics

Deep groove ball bearing is the most commonly used rolling bearing. The utility model has the advantages of simple structure and convenient use. It is mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has certain performance of angular contact ball bearing, and can bear combined radial and axial loads. When the speed is high and thrust ball bearing is not suitable, it can also be used to bear pure axial load. Compared with other types of bearings with the same specifications and sizes of deep groove ball bearings, this kind of bearings has smaller friction coefficient and higher limit speed. But it is not shock resistant and unsuitable to bear heavy loads.

When the deep groove ball bearing is mounted on the axle, the axial displacement of the axle or the housing can be limited within the axial clearance of the bearing, so it can be positioned in two directions. In addition, this kind of bearing also has a certain self-aligning ability. It can still work normally when the inclination is 2'-10'relative to the shell hole, but it has a certain impact on the bearing life.
