Deep groove ball bearings are mainly accommodate axial loads, but still can accommodate axial and radial load at the same time.
Deep groove ball bearings, with low friction coefficient and high tripping speed, with simple structure and low manufacturing cost, is easily to achieve high accuracy of manufacture.
