Ball bearings are used in machines which have lot of movement in their working process. Ball bearings reduce the friction during motion, so that efficiency of the machines is increased, and they move in a smooth manner.

Arguably the most common type of bearing, ball bearings are used in a wide variety of products and applications. From hard drives to skateboards, ball bearings are designed to handle both thrust and radial loads. However, ball bearings are usually found in applications with smaller loads.
