Why are ball bearings used in machinery class 8 physics CBSEHint: A ball bearing is a form of rolling-element bearing which uses balls to hold the bearing breed apart. A ball bearing is intended to reduce rotational friction and to accommodate radial and axial loads. It is done by using at least two races to hold the balls and distribute the loads through the ballsHow do ball bearings reduce friction? - Teachoo - ExtraJun 3, 2019 — When ball bearings are used, the bearings roll between the hub and axleSince rolling friction is less. To prevent that, we use ball bearings in the hub of the wheel. When ball bearings Next: Chapter 13 Class 8 - Sound→
