Deep groove ball bearing
Deep groove ball bearings are mainly subjected to radial loads and can also bear both radial and axial loads. When it is only subjected to radial loads, the contact angle is zero. When the deep groove ball bearing has a large radial clearance, it has the performance of angular contact bearing and can withstand large axial load. The deep groove ball bearing has a small friction coefficient and the limit rotation speed is also high.
