Types of Sheave Pulleys

1. Fixed Sheave Pulley

A fixed sheave pulley is designed to remain stationary while the rope or belt moves through it.

2. Movable Sheave Pulley

A movable sheave pulley can change its position to adjust the tension in the rope or belt.

3. Compound Sheave Pulley

A compound sheave pulley consists of multiple wheels in a single unit for increased mechanical advantage.

4. Snatch Sheave Pulley

A snatch sheave pulley is used for lifting heavy loads quickly and efficiently.

5. Wire Rope Sheave Pulley

6. Timing Belt Sheave Pulley

A timing belt sheave pulley is used in timing belt systems for precise and synchronous power transmission.

What is a sheave on a pulley

  • A sheave is a wheel or pulley with a grooved rim that is used to hold a belt, rope, or cable.
  • It is typically used to change the direction of a force or transmit power between the shaft and the belt/rope/cable.
  • Sheaves can be made from various materials such as steel, aluminum, or plastic depending on the application.
  • They come in different sizes and configurations to suit different types of pulley systems.
  • A sheave is an essential component in pulley systems for lifting, lowering, or transmitting power.

What are sheaves used for?

1. Load Distribution

Sheaves are used to distribute the load evenly across multiple ropes or belts for smoother operation.

2. Mechanical Advantage

By using compound sheave pulleys, mechanical advantage can be increased to lift heavier loads with less effort.

3. Direction Change

Sheaves are used to change the direction of a force to redirect the motion of the rope or belt.

4. Speed Adjustment

Adjusting the position of the movable sheave pulley can change the speed of the lifting operation.

5. Power Transmission

Sheaves are crucial for transmitting power from the driving shaft to the driven belt/rope/cable.

6. Tension Control

Sheaves help control the tension in the rope or belt to prevent slippage or breakage during operation.

Process of Sheave Pulley

The mold is prepared for the sheave pulley casting process.


The molten raw material is poured into the mold to form the sheave pulley shape.

Raw Materials

High-quality materials like steel or aluminum are used to ensure durability and strength.


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 with anti-rust coatings to enhance its longevity.

Separate Inspection

Individual inspection is done to check for any defects or irregularities in the sheave pulley.


Each sheave pulley is marked with identification for traceability and quality assurance.

How do you adjust sheave pulleys?

  • Locate the adjusting nut or screw on the sheave pulley mechanism.
  • Use the appropriate tool to turn the nut or screw clockwise or counterclockwise to adjust the position of the sheave.
  • Monitor the tension in the rope or belt as you adjust the sheave pulley to achieve the desired level.
  • Check the alignment of the sheave pulleys and make any necessary adjustments for smooth operation.
  • Test the lifting or power transmission system after adjusting the sheave pulleys to ensure proper functionality.
  • Regularly inspect and maintain the sheave pulleys to prevent wear and tear, and make further adjustments if needed.
