Question

Explain how ball bearing helps in reducing friction ??

Answer 1

Ball bearing reduces friction of certain moving parts by replacing sliding friction with rolling friction. They are used to provide better linear motion around a fix axis. Ball bearings are spheres that are held in a track.

Answer 2

Ball bearings are in contact in very less area and don't get time to interlock with irregularities on surface.hence, it reduces friction.
