The Working Principle
Deep groove ball bearing mainly bears the radial load, but also can bear both radial load and axial load. When it only bears the radial load, the contact angle is zero. When 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 small and the limit speed is high.
Deep groove ball bearings are the most commonly used rolling bearings. It is simple in structure and easy to use. It is mainly used to bear radial load, but when the radial clearance of bearing is increased, it has a certain performance of angular contact ball bearing and can bear combined radial and axial load. When the speed is high and the 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, the friction coefficient of these bearings is small and the limit speed is high. But not shock-resistant, not suitable for heavy load.
After the deep groove ball bearing is mounted on the shaft, the axial displacement of the shaft or shell in both directions can be restricted within the axial clearance range of the bearing, so it can be positioned in both directions. In addition, this kind of bearing also has a certain ability to adjust the center, when relative to the shell hole tilt 2 '~ 10', still can work normally, but has a certain impact on the bearing life.
