What is a sheave on a pulley

1. The sheave is the wheel part of the pulley that the belt wraps around.

It helps change the direction of force and transmit power efficiently.

2. It can be made of various materials such as steel, cast iron, or aluminum.

The material choice depends on the specific application and load requirements.

3. Sheaves come in different sizes and shapes depending on the intended use.

They can be flat, grooved, or V-shaped to accommodate different types of belts.

4. The sheave on a pulley plays a crucial role in the overall performance of the system.

It helps maintain tension in the belt and controls the speed of the machinery.

5. Proper maintenance and lubrication of the sheave are essential for optimal performance and longevity.

Regular inspection can help identify any wear or damage that may affect operation.

The initial mold is created based on the design specifications for the sheave pulley.


The molten metal is poured into the mold to form the desired shape of the sheave pulley.

Raw Materials

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


The sheave pulleys are manufactured using precision machining and quality control processes.


Each sheave pulley undergoes rigorous testing to ensure it meets quality and performance standards.

Antirust Treatment

Special coatings or treatments are applied to protect the sheave pulley from corrosion and rust.

Separate Inspection

Individual inspection is conducted to check for any defects or imperfections before final assembly.


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

How do you adjust sheave pulleys?

1. Loosen the set screws

Use the appropriate tool to loosen the set screws on the sheave pulley.

2. Adjust the position

Move the sheave pulley along the shaft to the desired position for speed adjustment.

3. Tighten the set screws

Once the desired position is achieved, tighten the set screws securely to hold the sheave in place.

4. Check alignment

Ensure the sheave pulley is aligned properly with the belt or rope for smooth operation.

5. Test the adjustment

Run the machinery to test the speed adjustment and make any necessary fine-tuning.

6. Regular maintenance

Periodically check and adjust the sheave pulleys to maintain optimal performance and efficiency.
