Write the importance of ball bearing in reducing rolling friction. Where the ball bearings commonly used.
Answers
Answer:
The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. ... Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each other.
Ball bearings use balls to separate two “races,” or bearing rings, to reduce surface contact and friction across moving planes.The rotation of the balls causes a reduced coefficient of friction when compared with flat surfaces rubbing against each other.
Ball bearings are used in devices that have a lot of motion in their cycle of operating. Ball bearings are the most common type of bearings and are found in many every day objects, such skateboards, blenders, bicycles, DVD players and photocopiers.
