Deep groove ball bearings are the widely used type of rolling bearings. These products are of simple design and easy to use.
To be mainly used to carry radial loads, This kind of bearing can have capability of angular contact ball bearings after the increase of radial clearance, thus can have the combined load of  both radial and axial directions. when the conditions has even very high speeds but hardly use thrust ball bearings in operation, this kind of bearing can be subjected to purely axial load.
