  • How ball bearings are manufactured | Engineering360

    What are ball bearings? Ball bearings are rolling-element bearings which use balls to maintain the separation and distance between the bearing races. They are designed to reduce rotational friction while supporting both radial and axial loads. The types of ball bearings that we think of today were initially manufactured at the end of the 19th century. The Welsh inventor Phillip Vaughan was given the first patent for ball bearings …
