The raw materials are melted and poured into the mold to create the sheave pulley’s shape and structure.

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 precision machinery and processes to meet quality standards.


Each sheave pulley undergoes rigorous testing to ensure it meets performance and safety requirements.

Antirust Treatment

The sheave pulley is treated with anti-rust coatings to protect it from corrosion and prolong its lifespan.

Separate Inspection

Each sheave pulley is individually inspected for quality control before being assembled into the conveyor system.


Each sheave pulley is marked with identification codes for traceability and quality assurance purposes.

How do you adjust sheave pulleys?

1. Tension Adjustment

Adjust the tension of the belt, rope, or chain by moving the sheave pulley closer or further apart.

2. Alignment Correction

Align the sheave pulleys with the shafts to ensure proper alignment and reduce wear on the system.

3. Lubrication Maintenance

Ensure proper lubrication of the sheave pulleys to reduce friction and extend their lifespan.

4. Inspection of Wear

Regularly inspect the sheave pulleys for signs of wear and replace them if necessary to maintain efficiency.

5. Speed Adjustment

Adjust the speed of the system by changing the diameter of the sheave pulleys to meet operational requirements.

6. Professional Assistance

If unsure, seek professional assistance to ensure proper adjustment and maintenance of sheave pulleys for optimal performance.
