Answer:
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.
Uses:- 1) it carries loads, reduces friction and positions moving machine parts.
2) ball bearings are rolling bearings that allow for a decrease in friction rotating between two surfaces; likely a vehicle and the pavement
3) Better sealing shield to prevent leaking of lubricant and avoid foreign particles entering the casing.
4) Easy bearing replacement.
5) Increase motor performance (less motor friction)
