The mold is created to shape the sheave pulley according to the desired specifications and design.


The molten raw materials are poured into the mold to form the shape of the sheave pulley.

Raw Materials

High-quality materials such as steel or aluminum are used to ensure durability and strength in the sheave pulley.


The sheave pulley is manufactured using advanced production techniques to meet industry standards.


Rigorous testing is conducted to ensure the sheave pulley meets quality and performance requirements.

Antirust Treatment

Special treatments are applied to the sheave pulley to prevent rust and corrosion, extending its lifespan.

Separate Inspection

Each sheave pulley undergoes individual inspection to guarantee quality control and consistency.


Identification markings are added to the sheave pulley for traceability and product information.

How do you adjust sheave pulleys?

1. Belt Tension Adjustment

Adjust the sheave pulley position to change the tension in the belt for optimal performance.

2. Diameter Adjustment

Changing the diameter of the sheave pulley alters the speed ratio and adjusts the machinery’s output speed.

3. Angular Positioning

Adjust the angle of the sheave pulley to control the belt’s alignment and improve power transmission.

4. Lubrication

Regularly lubricate the sheave pulley and belt to reduce friction and maintain smooth operation.

5. Alignment Check

Ensure the sheave pulleys are properly aligned to prevent belt slippage and premature wear.
