What is a sheave on a pulley?

  • A sheave on a pulley is a wheel with a groove around its circumference where a belt or rope can run.
  • It is used to change the direction of a belt or rope, providing mechanical advantage in various applications.
  • Sheaves are commonly found in pulley systems to transmit power and motion efficiently.
  • They can be made of various materials, such as steel, cast iron, or nylon, depending on the application.
  • Sheaves come in different sizes and designs to accommodate specific needs in different industries.

What are sheaves used for?

  • Power Transmission: Sheaves are used to transmit power from one source to another efficiently.
  • Direction Change: They help change the direction of a belt or rope in mechanical systems.
  • Tension Adjustment: Sheaves can be used to adjust the tension in a belt or rope system.
  • Speed Variation: By changing the diameter of the sheave, the speed of the system can be adjusted.
  • Load Distribution: Sheaves help distribute the load evenly across the belt or rope for smooth operation.
  • Noise Reduction: Properly designed sheaves can reduce noise and vibration in mechanical systems.

Process of Sheave Pulley


The mold for sheave pulleys is carefully crafted to ensure precision and consistency in the production process.

The raw materials are melted and poured into the mold to create the desired shape of the sheave pulley.

Raw Materials

We use high-quality materials such as steel and cast iron to ensure durability and performance of our sheave pulleys.


Our production process involves precision engineering and quality control measures to guarantee the reliability of our sheave pulleys.


Each sheave pulley undergoes rigorous testing to ensure it meets the highest standards of quality and performance.

Antirust Treatment

Our sheave pulleys are treated with an anti-rust coating to protect them from corrosion and extend their lifespan.

Seperate Inspection

Before packaging, each sheave pulley is inspected separately to ensure it meets our quality requirements.


Finally, each sheave pulley is marked with relevant information for easy identification and installation.

How do you adjust sheave pulleys?

  • Belt Tension: Adjust the position of the sheave to increase or decrease belt tension.
  • Sheave Diameter: Changing the sheave diameter can alter the speed of the system.
  • Alignment: Ensure the sheave pulleys are properly aligned for smooth operation.
  • Lubrication: Regularly lubricate the sheave pulleys to reduce friction and wear.
  • Inspect Regularly: Check the sheave pulleys for any signs of wear or damage and adjust accordingly.
  • Consult Manual: Refer to the manufacturer’s manual for specific instructions on adjusting sheave pulleys.
  • Professional Help: If unsure, seek help from a professional to adjust the sheave pulleys correctly.
