深沟球轴承主要承受径向载荷，也可同时承受径向载荷和轴向载荷。当其仅承受径向载荷时，接触角为零。
Deep groove ball bearings mainly bear radial load, but also can bear both radial load and axial load. When it only bears radial load, the contact angle is zero.
当深沟球轴承具有较大的径向游隙时，具有角接触轴承的性能，可承受较大的轴向载荷 ，深沟球轴承的摩擦系数很小，极限转速也很高。
When deep groove ball bearings have large radial clearance, they have angular contact bearing performance, can withstand large axial loads, the friction coefficient of deep groove ball bearings is very small, and the ultimate speed is also high.
