Deep groove ball bearings are mainly used to withstand pure radial load, but also to support radial and axial load. When only withstand pure radial load, the contact angle is zero. Performance of angular contact bearings, deep groove ball bearings with radial clearance, can bear large axial load. Deep groove ball bearing friction coefficient is small, the speed is also high, especially in the axial load is very high-speed operation conditions, more advantages than thrust ball bearings, deep groove ball bearings.
