Structure:
A typical ball bearing consists of the following components:
1. Inner Race (Inner Ring): The inner part that fits onto the rotating shaft.
2. Outer Race (Outer Ring): The outer part that is fixed in place, such as in a housing.
3. Balls: Spherical elements that roll between the inner and outer races, reducing friction.
4. Cage (Separator): A structure that holds the balls in place and ensures they are evenly spaced, allowing free and smooth movement.

Working Principle:
When the inner race rotates, the balls roll along the inner surface of the outer race. This rolling motion significantly reduces friction compared to sliding motion, leading to increased efficiency and reduced wear.
