Process of Compound Pulley

Mold

The first step is to create a mold that will be used to shape the pulley.

Casting

The molten material is poured into the mold to form the pulley shape.

Raw materials

High-quality materials are used to ensure durability and performance.

Production

The pulley is manufactured using precision machinery and techniques.

Testing

Each pulley undergoes rigorous testing to ensure quality and performance.

Antirust treatment

A special treatment is applied to prevent rust and corrosion.

Seperate inspection

Each pulley is inspected individually to meet quality standards.

Marking

Finally, the pulley is marked with necessary information for identification.

What is the function of the tensioner and idler pulley

1. Maintains proper tension in the belt
2. Guides the belt along the pulley system



3. Reduces vibrations and noise
4. Prevents belt slippage
5. Supports the belt during operation
6. Extends the life of the belt and other components
7. Ensures smooth and efficient operation of the system

How to stop a idler pulley from squeaking

1. Regular lubrication of the pulley
2. Check and replace worn-out bearings
3. Ensure proper alignment of the pulley
4. Tighten any loose bolts or screws
5. Inspect and replace the belt if necessary
