A Fan Drive Hub serves as the interface between the power source and the fan blades, allowing the transfer of rotational motion to create airflow for cooling. It is a cylindrical or disc-shaped component. The hub for the fan drive is often treated or coated to provide corrosion resistance. This helps protect the component from environmental elements, such as moisture and road salts, which can lead to corrosion and premature wear.

Attributes:
• Provide strength and heat resistance.
• Allows for easier maintenance and repair.

Applications:
A Fan Drive Hub is designed to provide a central connection point for attaching the fan blades securely.
