Ball bearings are a type of rolling-element bearing used to reduce friction and guide rotating parts. They allow for the injection of motion between different parts and transmit energy for mechanical operation. This type of bearing uses balls to maintain the separation and distance between the bearing races. Ball bearings are designed to reduce rotational friction while supporting both radial and axial loads. They are primarily made from steel, but other materials such as ceramic and nylon are available.
Ball bearings are used in a wide range of applications within the power transmission and manufacturing industries. You will find ball bearings in everything from vehicles and white goods to agriculture and aerospace machinery. There are a wide range of bearing types and sizes to suit all applications. Roller bearings are a similar rolling-element bearing which feature cylindrical rollers for supporting heavier loads.
