Question

what are ball bearings?? class 8 science

Answer 1

Explanation:

hi

A ball bearing is a type of rolling-element bearing that serves three main functions while it facilitates motion: it carries loads, reduces friction and positions moving machine parts. Ball bearings use balls to separate two “races,” or bearing rings, to reduce surface contact and friction across moving planes.

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.
