Deep groove ball bearings are simple in design, non-separable, suitable for high and very high speeds and are robust in operation, requiring little maintenance. They are the most widely used bearing type.
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 bearings with a large radial clearance, the same as angular contact bearing performance, can withstand greater axial load, The friction coefficient is very small, and the limit speed is also high.
