Answer 1

Answer:

Use in machines: The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. ... Ball bearings reduce the friction so that machinery can work smoothly. The sliding friction gets converted to rolling friction which is much less and power dissipation is reduced.
