Why are ball bearings used to reduce friction?

Marbles illustrate the action of ball bearings | Friction | PhysicsJun 27, 2013 — This is the basis of the ball-bearing, which This greatly reduces the friction between the surfaces and correspondingly the effort needs to 

Ball bearing - WikipediaThe purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each otherThe role of the structure and parts in reducing friction / BearingAug 20, 2019 — Table 1 shows the "balls" and "rollers" used as rolling elements. Table 1: The different shapes of rolling elements. Ball, Ball bearing. Cylindrical 

The fall of friction in bearings? | Bearing TipsSep 10, 2019 — While this is a good way of reducing wear and preventing corrosion, there are new materials that, when used on bearings, dramatically reduce 

BearingsA bearing is a component used to reduce friction and to maintain clearance are commonly made with hardened rolling elements (balls and rollers) and racesBall bearings reduce friction because they - - - - - rather thanBall bearing reduce friction because they roll rather than slide.
