Deep groove ball bearings mainly bear radial load, and can also carry radial load and axial load at the same time. When it is only subjected to radial loads, the contact angle is zero. When a deep groove ball bearing has an ample radial clearance, it has the performance of an angular contact bearing and can withstand a large axial load. The deep groove ball bearing has a small friction coefficient and a high limit speed.
Characteristics of deep groove ball bearings
Deep groove ball bearings are the most commonly used rolling bearings. Its structure is simple and easy to use. It is mainly used to bear radial loads, but when the bearing radial clearance is increased, it has an absolute angular contact ball bearing performance and can carry combined radial and axial loads. It can also be used to take the pure axial load when the speed is high, and the thrust ball bearing is not suitable. Compared with other types of bearings with the same specifications as deep groove ball bearings, this type of bearing has a small friction coefficient and high limiting speed. But it is not resistant to impact and is not suitable for heavy loads.
After the deep groove ball bearing is installed on the shaft, the axial displacement of the rod or the housing can be limited in the axial clearance of the bearing so that it can be axially positioned in both directions. In addition, this type of bearing also has a specific self-aligning ability. When it is inclined 2 ′ to 10 ′ relatives to the housing hole, it can still work usually, but it has a particular impact on the bearing life.
