What is a Sheave on a Pulley

  • Definition: A sheave on a pulley is a wheel with a groove used to hold a belt, rope, or cable to transmit power.
  • Function: The sheave provides a contact point for the belt or rope, allowing it to move and transmit power efficiently.
  • Material: Sheaves are typically made from materials like steel, aluminum, or plastic depending on the application.
  • Size: Sheaves come in various sizes and diameters to accommodate different belt or rope sizes.
  • Usage: Sheaves are commonly used in various industries for power transmission, lifting, and conveying applications.

What are Sheaves Used For?

  • Power Transmission: Sheaves are used to transmit power from one rotating element to another.
  • Lifting Applications: Sheaves are utilized in lifting systems to change the direction of force and increase mechanical advantage.
  • Conveying Systems: Sheaves are employed in conveyor systems to move materials from one place to another.

High-quality raw materials are melted and poured into the mold to create the sheave pulley shape with precision.

Raw Materials

Sheave pulleys are made from materials like steel, aluminum, or plastic, selected based on the intended use and durability requirements.


The production process involves machining, finishing, and quality control checks to ensure each sheave pulley meets the required specifications.


Each sheave pulley undergoes rigorous testing to ensure its performance, durability, and alignment meet industry standards.

Antirust Treatment

Sheave pulleys are treated with anti-rust coatings to protect them from corrosion and extend their lifespan.

Separate Inspection

After production, each sheave pulley undergoes a separate inspection process to identify any defects or issues before packaging.


Finally, each sheave pulley is marked with relevant information such as size, material, and production date for easy identification and traceability.

How do you adjust Sheave Pulleys?

  • Loosening the Set Screw: To adjust the position of the sheave pulley, first, loosen the set screw using the appropriate tool.
  • Adjusting the Position: Move the sheave pulley to the desired position by sliding it along the shaft or rotating it as needed.
  • Retightening the Set Screw: Once the adjustment is made, securely tighten the set screw to lock the sheave pulley in place.
  • Checking Alignment: After adjustment, ensure that the sheave pulley is properly aligned with other components for optimal performance.
  • Testing Operation: Test the operation of the sheave pulley to ensure that the adjustment has been successful and there are no issues.
  • Regular Maintenance: Periodically check and adjust sheave pulleys as needed to maintain smooth operation and prevent premature wear.
  • Consulting a Professional: If unsure about how to adjust sheave pulleys, consider seeking assistance from a qualified technician or mechanic.
