Process of Sheave Pulley


The mold is created to form the shape of the sheave pulley.


The molten material is poured into the mold to create the pulley’s structure.

Raw Materials

High-quality materials are used to ensure the durability and performance of the sheave pulley.


The pulley is manufactured with precision engineering techniques to meet quality standards.


Each sheave pulley undergoes rigorous testing to ensure reliability and performance.

Antirust Treatment

A special treatment is applied to protect the sheave pulley from corrosion and rust.

Separate Inspection

Individual inspection is conducted to guarantee the quality of each sheave pulley.


Each sheave pulley is marked with relevant information for identification and traceability.

How do you adjust sheave pulleys?

1. Loosen the set screws or bolts holding the sheave in place.

2. Adjust the position of the sheave along the shaft to the desired location.

3. Tighten the set screws or bolts securely to hold the sheave in place.

4. Check the alignment of the sheave with other pulleys in the system.

5. Verify the tension of the belt or cable on the sheave for optimal performance.

6. Regularly inspect and maintain the sheave pulleys to ensure smooth operation.
