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

Deep groove ball bearings with other types of simple structure, easy to achieve higher than the manufacturing precision, so easy to series of mass production, the manufacturing cost is low, use very common. Deep groove ball bearings, there are all kinds of basic except the variant structure.
