The mold is created based on the design specifications for the sheave pulley.


The molten metal is poured into the mold to form the shape of the sheave pulley.

Raw Materials:

High-quality materials like steel or aluminum are used to ensure strength and durability.


The sheave pulleys are manufactured using precision engineering and quality control measures.


Each sheave pulley undergoes rigorous testing to ensure performance and safety standards are met.

Antirust Treatment:

Special coatings are applied to prevent corrosion and extend the lifespan of the sheave pulley.

Separate Inspection:

Each sheave pulley is individually inspected for quality before packaging and shipping.


Identification marks are added to the sheave pulley for easy identification and traceability.

How do you adjust sheave pulleys?

1. Loosen the Set Screws:

Use the appropriate tools to loosen the set screws holding the sheave in place.

2. Adjust the Position:

Move the sheave along the shaft to the desired position for proper alignment.

3. Tighten the Set Screws:

Securely tighten the set screws to hold the sheave in place and prevent slippage.

4. Check Alignment:

Ensure the sheave is aligned with other components for smooth operation.

5. Test the Pulley:

Rotate the pulley manually or with the equipment to confirm proper adjustment.
