What is a Sheave on a Pulley?

1. Definition

A sheave on a pulley is a grooved wheel or pulley designed to hold a belt, chain, or rope to transmit power or motion.

2. Function

Sheaves on pulleys help guide and support the belt or rope, ensuring smooth and efficient power transmission in printing presses.

3. Types

Sheaves on pulleys come in various shapes and sizes, depending on the specific application and requirements of the printing press.

4. Materials

Sheaves on pulleys are typically made of durable materials such as steel, cast iron, or aluminum to withstand high loads and operating conditions.

5. Maintenance

Regular inspection and lubrication of sheaves on pulleys are essential to ensure optimal performance and longevity of printing press systems.

What are Sheaves Used For?

1. Power Transmission

Sheaves are used for transmitting power from one rotating element to another in printing press machinery.

2. Speed Control

Sheaves are used to control the speed of printing press components by adjusting the diameter of the sheave pulley.

3. Tensioning

Sheaves are used for tensioning belts or ropes in printing press systems to maintain proper alignment and prevent slippage.

The raw materials are melted and poured into the mold to create the desired shape of the sheave pulley.

Raw Materials

High-quality materials such as steel or aluminum are used to manufacture sheave pulleys for printing presses.


The production process involves machining and finishing the sheave pulleys to meet specific requirements and standards.


Each sheave pulley undergoes rigorous testing to ensure quality, performance, and durability in printing press applications.

Antirust Treatment

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

Separate Inspection

Every sheave pulley is individually inspected for defects or imperfections before being approved for use in printing presses.


Sheave pulleys are marked with identifying information such as part numbers or specifications for easy identification and tracking.

How do you adjust sheave pulleys?

1. Belt Tension

Adjust the sheave pulley position to achieve the desired belt tension for optimal performance.

2. Sheave Alignment

Ensure the sheave pulleys are properly aligned to prevent belt slippage and ensure smooth operation.

3. Lubrication

Regularly lubricate the sheave pulleys to reduce friction and wear on printing press components.

4. Inspection

Inspect the sheave pulleys regularly for signs of wear, damage, or misalignment, and adjust as needed.

5. Size Adjustment

Adjust the size of the sheave pulleys to control the speed or power transmission in printing press machinery.

6. Consultation

If unsure about how to adjust sheave pulleys, consult the manufacturer’s guidelines or seek professional assistance.
