Antirust Treatment

The drive pulley is treated with anti-rust coatings for durability.

Separate Inspection

Each drive pulley is individually inspected for quality control.


The drive pulley is marked with relevant information for identification.

What is the difference between a drive pulley and a head pulley?

1. Position

The drive pulley is located at the motor end, while the head pulley is at the discharge end of the conveyor.

2. Function

The drive pulley transmits power, while the head pulley redirects the belt.

3. Size

The drive pulley is usually larger in diameter compared to the head pulley.

4. Material

The drive pulley is often made of steel or aluminum, while the head pulley may be made of rubber or other materials.

5. Belt Contact

The drive pulley has direct contact with the belt, while the head pulley guides the belt along the conveyor.

6. Rotation

The drive pulley is powered to rotate, while the head pulley rotates freely.

7. Location

The drive pulley is typically located at the beginning of the conveyor system, while the head pulley is at the end.
