Fixed eye pulleys are equipped with a fixed eye for easy attachment to ropes, cables, or other gear, providing stability and security during lifting operations.

What is a sheave on a pulley?

1. Definition

A sheave on a pulley is a wheel with a groove used to guide a rope or cable, providing support and direction for lifting or pulling applications.

2. Function

The sheave helps to minimize friction and wear on the rope or cable, allowing for smoother and more efficient operation of the pulley system.

3. Components

The sheave is typically made of metal or durable plastic and is mounted on a shaft within the pulley frame for rotation.

4. Size

Sheaves come in various sizes to accommodate different rope or cable diameters, ensuring a proper fit for the specific application.

5. Maintenance

Regular inspection and lubrication of the sheave are essential to ensure optimal performance and longevity of the pulley system.

What are sheaves used for?

1. Load Distribution

Sheaves are used to distribute the weight of a load evenly across multiple ropes or cables, reducing strain and wear on individual components.

2. Direction Change

Sheaves are utilized to change the direction of a rope or cable, allowing for efficient and controlled movement of loads in various directions.

3. Mechanical Advantage

By incorporating sheaves into a pulley system, users can gain a mechanical advantage to lift heavier loads with less effort.

4. Tension Adjustment

Sheaves can be used to adjust the tension in a rope or cable, providing flexibility and control in lifting or pulling operations.

5. Speed Control

Sheaves help to regulate the speed of the pulley system, allowing for precise and controlled movements during lifting or lowering tasks.

6. Support and Guidance

Sheaves provide support and guidance for ropes or cables, ensuring smooth and reliable operation of the pulley system in various applications.

Process of Sheave Pulley

The mold for sheave pulleys is carefully crafted to create the desired shape and dimensions of the pulley.


During casting, molten metal is poured into the mold to form the solid structure of the sheave pulley.

Raw Materials

High-quality materials such as steel or aluminum are used to ensure the strength and durability of the sheave pulley.


The production process involves machining and finishing the sheave pulley to meet the specified requirements and standards.


Each sheave pulley undergoes rigorous testing to ensure it meets safety and performance standards before being released for use.

Antirust Treatment

Special coatings or treatments are applied to the sheave pulley to protect it from corrosion and extend its lifespan.

Separate Inspection

Individual inspection of each sheave pulley is conducted to check for any defects or irregularities before packaging and shipment.


Each sheave pulley is marked with essential information such as size, load capacity, and manufacturer details for easy identification and traceability.

How do you adjust sheave pulleys?

1. Loosen the Set Screw

To adjust a sheave pulley, first, loosen the set screw that secures the pulley in place on the shaft.

2. Slide the Sheave

Once the set screw is loose, slide the sheave along the shaft to the desired position for proper tension adjustment.

3. Retighten the Set Screw

After adjusting the sheave, retighten the set screw securely to hold the pulley in the new position and maintain proper tension.

4. Check Alignment

Ensure that the sheave is properly aligned with other components in the pulley system to prevent any issues during operation.

5. Test Operation

After adjusting the sheave pulley, test the operation of the pulley system to confirm that it functions smoothly and efficiently.

6. Regular Maintenance

Regularly inspect and adjust sheave pulleys as needed to ensure optimal performance and longevity of the pulley system.
