What is a sheave on a pulley?

  • 1. Definition: A sheave on a pulley is a grooved wheel that holds a belt, rope, or cable, allowing it to move smoothly and efficiently.
  • 2. Function: Sheaves help to change the direction of the force applied and transmit power between rotating shafts.
  • 3. Components: Sheaves consist of a grooved wheel, a central hub, and sometimes bearings for smooth rotation.
  • 4. Types: Sheaves come in various types, such as V-belt, flat belt, timing belt, wire rope, chain, and variable pitch sheaves.
  • 5. Importance: Sheaves play a crucial role in pulley systems by guiding and supporting belts, ropes, or cables for efficient power transmission.

What are sheaves used for?

1. Power Transmission

Sheaves are used to transmit power between rotating shafts by guiding belts, ropes, or cables.

2. Direction Changes

Sheaves help to change the direction of the force applied in pulley systems, allowing for efficient operation.

3. Load Support

Sheaves support and guide heavy loads in lifting and rigging applications, ensuring safe and reliable operation.

4. Speed Control

Variable pitch sheaves allow for adjustable speed ratios, providing control over the speed of machinery.

Process of Sheave Pulley


The mold for sheave pulleys is created to form the desired shape and dimensions of the sheave.


The molten raw materials are poured into the mold to create the sheave pulley’s solid form.

Raw Materials

High-quality materials such as steel or aluminum are used to ensure durability and performance.


The sheave pulleys are manufactured following precise production processes to meet industry standards.


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

Antirust Treatment

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

Separate Inspection

Each sheave pulley is individually inspected to ensure it meets all specifications and quality requirements.


Sheave pulleys are marked with necessary information such as size, load capacity, and production details for identification.

How do you adjust sheave pulleys?

  • 1. Belt Tension: Adjust the tension of the belt connected to the sheave pulley for optimal performance.
  • 2. Sheave Alignment: Ensure the sheave pulleys are correctly aligned to avoid unnecessary wear and tear.
  • 3. Lubrication: Properly lubricate the sheave pulleys to reduce friction and improve efficiency.
  • 4. Check for Wear: Regularly inspect the sheave pulleys for signs of wear and replace them if necessary.
  • 5. Adjust Speed Ratio: Use variable pitch sheaves to adjust the speed ratio of the pulley system as needed.
  • 6. Consult Manual: Refer to the manufacturer’s manual for specific instructions on adjusting sheave pulleys.
  • 7. Seek Professional Help: If unsure, seek assistance from a qualified technician to adjust sheave pulleys correctly.
