- Ball Bearing: Ball bearings are primarily designed to support radial loads, with some variations capable of handling light axial loads. They are widely used in applications where smooth and efficient rotation is essential, such as in machinery, equipment, and automotive components.

In summary, the function of a deep groove ball bearing includes supporting radial and axial loads, reducing friction, enabling smooth rotation, distributing loads, and facilitating proper lubrication. These functions make deep groove ball bearings essential components in a wide range of machinery and equipment across various industries.
