About Ball Bearing:

Ball bearings are mechanical components that are used to reduce friction between two surfaces that are in contact with each other. They are made up of a number of small metal balls that are housed in a circular metal track, known as a raceway. The balls are typically made from steel or ceramic materials, and the raceway is usually made from hardened steel.

When two surfaces come into contact with each other, they create a lot of friction, which can cause wear and tear on the surfaces and reduce their lifespan. Ball bearings are designed to reduce this friction by allowing the two surfaces to roll over each other instead of sliding against each other. This rolling action creates less friction, which in turn reduces wear and tear and increases the lifespan of the surfaces.
