Companion Sheave

1. Increased Efficiency

Companion sheaves are designed to increase the efficiency of a pulley system by reducing friction and allowing for smoother operation.

2. Load Distribution

These sheaves help distribute the load evenly across the pulley, preventing premature wear and tear on the system.

3. Noise Reduction

By providing a smoother operation, companion sheaves help reduce noise levels in the pulley system, creating a more pleasant working environment.

4. Extended Lifespan

Due to their ability to reduce friction and wear, companion sheaves can extend the lifespan of the entire pulley system.

5. Versatility

Companion sheaves come in a variety of sizes and designs, making them suitable for a wide range of applications and industries.

3. Wire Rope Sheave Pulleys

Wire rope sheave pulleys are specifically designed to guide and support wire ropes in lifting and rigging operations.

4. Chain Sheave Pulleys

Chain sheave pulleys are used with chains to transmit power and motion in heavy-duty and high-load applications.

5. Flat Belt Sheave Pulleys

Flat belt sheave pulleys are ideal for applications where a flat belt is used to transmit power, such as in conveyor systems and agricultural equipment.

6. Grooveless Sheave Pulleys

Grooveless sheave pulleys are designed without grooves and are used in applications where a smooth surface is required to prevent damage to the material being transported.

What is a Sheave on a Pulley

1. Definition

A sheave on a pulley is a wheel with a groove around its circumference, designed to hold a belt, rope, or cable to enable mechanical power transmission.

2. Function

The sheave on a pulley helps guide and support the belt, rope, or cable, ensuring proper alignment and tension for efficient power transmission.

3. Material

Sheaves on pulleys are commonly made of materials such as steel, aluminum, or plastic, depending on the application and load requirements.

4. Design

The design of the sheave on a pulley can vary based on the type of belt or rope being used, as well as the specific requirements of the machinery or equipment.

5. Maintenance

Regular inspection and maintenance of the sheave on a pulley are essential to ensure smooth operation and prevent premature wear and tear on the system.

What are Sheaves Used For?

1. Power Transmission

Sheaves are used to transmit power from one rotating shaft to another, allowing for the movement of machinery and equipment.

2. Load Distribution

Sheaves help distribute the load evenly across the pulley system, reducing stress and wear on individual components.

3. Speed Variation

By changing the diameter of the sheave, speed variation can be achieved in the pulley system, allowing for different operating speeds.

4. Directional Changes

Sheaves can be used to change the direction of the belt, rope, or cable, enabling the machinery to operate in different directions.

5. Tension Control

Sheaves help control the tension of the belt, rope, or cable, ensuring proper alignment and preventing slipping or breakage.

6. Noise Reduction

Sheaves can help reduce noise levels in the pulley system by providing smoother operation and reducing friction.

Process of Sheave Pulley

The mold for the sheave pulley is carefully designed to ensure the precise shape and dimensions of the final product.


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

Raw Materials

The raw materials used for sheave pulleys can vary, with common materials including steel, aluminum, and plastic.


The production process involves shaping, machining, and finishing the sheave pulley to meet quality standards and specifications.


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

Antirust Treatment

Sheave pulleys may receive antirust treatment to protect them from corrosion and ensure a longer lifespan in various operating environments.

Seperate Inspection

Each sheave pulley is individually inspected to check for any defects or imperfections that may affect its performance or safety.


Once the sheave pulley passes all quality checks, it is marked with relevant information such as size, load capacity, and production date for identification purposes.

How do you adjust Sheave Pulleys?

1. Tension Adjustment

To adjust the tension of the sheave pulleys, you can use tools such as tension gauges to measure and set the correct tension for optimal performance.

2. Alignment Correction

If the sheave pulleys are not aligned properly, you can adjust their position using alignment tools to ensure smooth operation and prevent premature wear.

3. Diameter Modification

Changing the diameter of the sheave pulleys can adjust the speed and power transmission capabilities of the system, allowing for customization based on specific requirements.

4. Lubrication Maintenance

Regular lubrication of the sheave pulleys can help reduce friction and wear, ensuring smooth operation and prolonging the lifespan of the system.

5. Inspection and Replacement

Periodic inspection of the sheave pulleys is essential to identify any signs of wear or damage, and timely replacement of worn-out components can prevent system failure.

6. Consultation with Experts

If you are unsure about how to adjust sheave pulleys properly, it is recommended to consult with industry experts or manufacturers for guidance and assistance.
