Deep groove ball bearing 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 bearing have large radial clearance, they have angular contact bearing performance, can withstand large axial loads, the friction coefficient of deep groove ball bearing is very small, and the ultimate speed is also high.
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. Thrust ball bearing can also be used to withstand pure axial loads when the rotating speed is high and thrust ball bearing are not suitable. Compared with other types of bearing with the same specifications and sizes of deep groove ball bearing, this kind of bearing 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 shaft, the axial displacement of the shaft or the shell 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.
