Question

why do ball bearings fitted in the axel of vehicles reduce friction ?

Answer 1

The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. ... As one of the bearing races rotates it causes the balls to rotate as well. Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each other.

Answer 2

Hi _______HERE IS YOUR ANSWER.

Ballbearing fitted in the axel of vehicle to reduce friction because it reduces the sliding friction into rolling friction and provide better linear motion and rotation motion in a fixed axis.
