A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races.
USES
Ball bearings are used for rolling elements, such as skateboard wheels or the rotating parts of computer hard drives, or axial devices, such as a sliding drawer. They are generally designed to bear light loads, as heavy stress can cause the balls inside the bearings to become warped. Because of their limitations, ball bearings are usually used to roll or rotate lightweight objects.
