What is a Sheave on a Pulley?

  • A sheave is a wheel with a grooved rim used in conjunction with ropes or belts to change the direction of force or transmit power.
  • It helps to reduce friction and wear on the rope or belt, extending their lifespan.
  • Sheaves can be made from various materials such as metal, plastic, or ceramic, depending on the application.
  • They come in different sizes and configurations to accommodate different rope or belt diameters.
  • Sheaves are essential components in pulley systems for lifting, lowering, or transmitting power.

What are Sheaves Used For?

  • Changing the direction of force in lifting and hoisting applications.
  • Transmitting power between shafts in machinery and equipment.
  • Supporting and guiding ropes or belts to prevent slippage or misalignment.
  • Adjusting the speed or torque of rotating equipment by varying the sheave diameter.
  • Compensating for misalignment or vibration in mechanical systems.
  • Reducing wear and tear on ropes or belts to prolong their lifespan.

Process of Sheave Pulley


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

The molten metal is poured into the mold to create the desired shape of the sheave pulley.

Raw Materials:

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


The sheave pulley is manufactured using advanced techniques and machinery for consistency and quality.


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

Antirust Treatment:

The sheave pulley is treated with anti-rust coatings to protect it from corrosion and environmental damage.

Separate Inspection:

Each sheave pulley is individually inspected to guarantee quality and precision before assembly.


Final markings are added to the sheave pulley for identification and traceability purposes.

How do you Adjust Sheave Pulleys?

  • Loosen the set screws on the sheave to release tension on the belt or rope.
  • Rotate the sheave to adjust the speed or torque as needed.
  • Check the alignment of the sheave with other pulleys in the system.
  • Ensure the belt or rope is properly tensioned for optimal performance.
  • Tighten the set screws back in place once adjustments are made.
  • Test the system to verify that the sheave pulleys are functioning correctly.
  • Regularly inspect and maintain the sheave pulleys to prevent premature wear or damage.
