A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races.

The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. 

Can be used in projects, computer fans and spinning devices, skateboards, motorcycles, fidgets, hobbies, cars, machines, pumps, and a wide range of applications.
