Deep groove ball bearings are used to withstand pure radial load, also can both radial load and axial load. When the only subject to pure radial load, the contact Angle is zero. When deep groove ball bearing has bigger radial clearance, have angular contact bearing performance and can withstand the larger axial load. Deep groove ball bearings of the friction coefficient is small, limit speed is very high also, especially in the axial load big high-speed operation conditions, deep groove ball bearing than thrust ball bearings are more superiority.
