Question

We use ball bearings to friction

Answer 1

The 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 other❤❣❤❣❤❣❤❣❤❣❤
