Tapered sheave pulleys are tapered for better belt alignment and reduced slippage in printing press applications.

What is a sheave on a pulley?

  • Definition: A sheave on a pulley is a grooved wheel designed to hold a belt, rope, or cable to facilitate power transmission.
  • Function: The sheave provides a surface for the belt to grip, allowing for the transfer of motion and power between two points.
  • Types: Sheaves can come in various designs such as V-belt sheaves, timing belt sheaves, and flat belt sheaves, among others.
  • Materials: Sheaves are typically made from materials like steel, aluminum, or plastic, depending on the application.
  • Importance: Sheaves play a crucial role in the smooth operation and efficiency of machinery like printing presses.

What are sheaves used for?

1. Power Transmission

Sheaves are used to transmit power from one rotating element to another, such as in printing press machinery.

2. Belt Tensioning

Sheaves help maintain proper belt tension for efficient operation and prevent slippage in printing press applications.

3. Speed Control

Sheaves allow for speed control by adjusting the diameter of the sheave to regulate the speed of the printing press.

4. Load Distribution

Sheaves distribute the load evenly across the belt to prevent premature wear and ensure consistent performance.

5. Direction Change

Sheaves can change the direction of motion in printing press equipment by guiding the belt along the desired path.

6. Noise Reduction

Sheaves help reduce noise and vibration in printing presses by providing smooth and efficient power transmission.

Process of Sheave Pulley


The mold is created to form the shape of the sheave pulley for printing presses.

The molten raw materials are poured into the mold to cast the sheave pulley in the desired shape.

Raw Materials

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


The sheave pulley is manufactured using precision engineering techniques to meet quality standards.


Each sheave pulley undergoes rigorous testing to ensure proper functionality and performance in printing press applications.

Antirust Treatment

The sheave pulley is treated with anti-rust coating to protect it from corrosion and extend its lifespan.

Separate Inspection

Each sheave pulley is inspected individually to guarantee quality and performance before being shipped.


The sheave pulley is marked with relevant information such as size, model, and specifications for identification purposes.

How do you adjust sheave pulleys?

1. Loosen the Set Screw

Start by loosening the set screw on the sheave pulley hub to allow for adjustment.

2. Position the Sheave

Adjust the position of the sheave on the shaft to achieve the desired belt tension and alignment.

3. Tighten the Set Screw

Once the sheave is properly positioned, tighten the set screw to secure it in place.

4. Check Alignment

Verify that the sheave is aligned with other pulleys and the belt for smooth operation.

5. Test Operation

Run the printing press machinery to test the operation of the sheave pulleys and make any necessary adjustments.

6. Regular Maintenance

Regularly check and adjust the sheave pulleys to ensure optimal performance and prevent premature wear.
