Question

explain the principal of ball bearing to reduce​

Answer 1

Answer:

On the principle that rolling friction is less than sliding friction. Think of ball bearings as little wheels inside of the machine.

Answer 2

Explanation:

Bearings reduce friction by means of a rolling motion Bearings reduce friction by means of this rolling motion. The "rolling bearing", with its rolling motion, reduces friction more than the "plain bearing" with its sliding motion, allowing for a greater decrease in the amount of energy consumption during rotation.
