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


During casting, the molten material is poured into the mold to create the sheave pulley.

Raw Materials

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


The production process involves machining and assembly of the components to create the final product.


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

Antirust Treatment

Antirust treatment is applied to the sheave pulley to protect it from corrosion and extend its lifespan.

Separate Inspection

Each sheave pulley is inspected individually to identify any defects or irregularities before shipping.


After inspection, the sheave pulley is marked with relevant information for identification and traceability.

How do you adjust sheave pulleys?

1. Tension Adjustment

Adjust the tension of the belt or rope on the sheave pulley to ensure proper alignment and operation.

2. Positioning

Position the sheave pulley correctly on the shaft to maintain proper alignment with other components.

3. Lubrication

Ensure the bearings and moving parts of the sheave pulley are adequately lubricated for smooth operation.

4. Belt Alignment

Check and adjust the alignment of the belt on the sheave pulley to prevent slippage and wear.

5. Inspection

Regularly inspect the sheave pulley for signs of wear, damage, or misalignment, and make necessary adjustments.

6. Professional Assistance

If unsure, seek professional help to adjust sheave pulleys correctly and avoid causing further damage.
