The function of ball bearings in a wheel is :
To increase friction
To convert kinetic friction into rolling friction
To convert static friction into kinetic friction
Just for convenience
To convert kinetic friction into rolling friction
A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. In general, itโs main function is to convert kinetic friction into rolling friction. It achieves this by using at least two races to contain the balls and transmit the loads through the balls.
