What is a sheave on a pulley?

  • A sheave is a wheel or pulley with a grooved rim designed to hold a belt, rope, or cable.
  • sheave pulley

  • It is used to change the direction of a moving belt or to transmit power between the shaft and the belt.
  • Sheaves are commonly found in various industrial machinery and equipment.
  • They come in different sizes and materials to suit specific applications and load requirements.
  • Sheaves play a crucial role in ensuring smooth and efficient power transmission.

What are sheaves used for?

1. Power Transmission

Sheaves are used to transmit power from one rotating shaft to another using belts, ropes, or chains.

2. Direction Change

They are used to change the direction of motion in machinery and equipment.

3. Tensioning

Sheaves help maintain tension in belts and ropes for optimal performance.

4. Speed Adjustment

Variable speed sheave pulleys allow for adjusting the speed of machinery as needed.

5. Load Handling

Sheaves are used in lifting and pulling applications to handle heavy loads efficiently.

6. Synchronization

Timing belt sheave pulleys ensure precise synchronization in machinery and equipment.

Process of Sheave Pulley

Raw Materials

Ductile iron is commonly used for its strength and durability in sheave pulley production.


The sheave pulley is manufactured with precision engineering and quality control measures.


Each sheave pulley undergoes rigorous testing to ensure performance and reliability.

Antirust Treatment

The sheave pulley is treated to prevent corrosion and ensure longevity.

Separate Inspection

Every sheave pulley is individually inspected to meet quality standards.


Identification marks are added for traceability and quality assurance.

How do you adjust sheave pulleys?

1. Belt Tension Adjustment

Adjust the tension of the belt connected to the sheave pulley for optimal performance.

2. Sheave Alignment

Ensure the sheave pulleys are properly aligned to prevent wear and tear on belts.

3. Lubrication

Regularly lubricate the sheave pulleys to reduce friction and extend their lifespan.

4. Inspection

Inspect the sheave pulleys regularly for any signs of wear or damage and adjust accordingly.

5. Temperature Control

Monitor the temperature around the sheave pulleys to prevent overheating and ensure smooth operation.

6. Consult Manufacturer’s Guidelines

Refer to the manufacturer’s guidelines for specific instructions on adjusting sheave pulleys.
