Ball bearing - Wikipedia

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.

Ball bearings and bearing balls: American Journal of

Dec 23, 2020· The bearing is constructed with an inner and outer race containing a nuer of steel balls that help to reduce friction by rolling around the race. The balls themselves are not ball bearings. Rather, they are bearing balls usually made of steel, but ceramic balls can also be used, allowing the bearing to spin faster since the balls are lighter.
