Function of Bike Ball Bearings

Ball bearings operate by distributing weight and reducing friction between rotating components. They consist of:

• Inner Race: Fits onto the axle or shaft.
• Outer Race: Attaches to the housing or frame.
• Balls: Roll between the inner and outer races, reducing friction.

As the bike moves, the balls roll smoothly, minimizing resistance and allowing for efficient pedaling.
