   working principle
    Deep groove ball bearings mainly take radial load, but also to support radial and axial load. When the only bear radial load, the contact angle is zero. When the deep groove ball bearings with a larger radial clearance, the performance with angular contact bearings can bear large axial load, deep groove ball bearing friction coefficient is small, speed is also high.
