Deep groove ball bearing is the most representative rolling bearing.
Compared with other types of bearings with the same size, the deep groove ball bearing has small friction coefficient, high limit speed, simple structure, low manufacturing cost, high accuracy, no need for regular maintenance, large size range, and many forms. It is the most widely used type of bearing.
Deep groove ball bearings mainly bear radial load, but also can bear certain axial load.
When the deep groove ball bearing bears the radial load, the contact angle is zero.
