Types of Sheave Pulleys

1. Fixed Pulleys

Fixed pulleys have a stationary axle and are used to change the direction of a force.

2. Movable Pulleys

Movable pulleys have a pulley that moves with the load, reducing the amount of force needed.

3. Compound Pulleys

Compound pulleys combine fixed and movable pulleys to provide mechanical advantage.

4. Block and Tackle Pulleys

Block and tackle pulleys use multiple pulleys to increase the mechanical advantage for lifting heavy loads.

5. Timing Belt Pulleys

Timing belt pulleys are used with timing belts to transfer motion between two shafts.

6. Wire Rope Pulleys

Wire rope pulleys are specifically designed to work with wire ropes for lifting and pulling applications.

What is a Sheave on a Pulley

1. Definition

A sheave on a pulley is a wheel with a groove used to guide and support a belt, rope, or cable.

2. Function

The sheave provides a means of transmitting power and changing the direction of motion in a pulley system.

3. Components

Sheaves typically consist of a wheel, axle, and bearings to facilitate smooth rotation.

4. Applications

Sheaves are commonly used in various industries such as manufacturing, construction, and transportation.

5. Sizes

Sheaves come in different sizes to accommodate various belt or rope diameters and load capacities.

What are Sheaves Used For?

1. Load Distribution

Sheaves help distribute loads evenly across multiple lines or ropes in a pulley system.

2. Mechanical Advantage

By using multiple sheaves, mechanical advantage can be gained to lift heavy loads with less effort.

3. Directional Changes

Sheaves are used to change the direction of a force or motion in a pulley system.

4. Speed Adjustment

Sheaves can be adjusted to change the speed of the system by altering the diameter of the sheave.

5. Tension Control

Sheaves help control the tension in a belt or rope, ensuring smooth operation and preventing slippage.

6. Power Transmission

Sheaves transmit power from one shaft to another, allowing for efficient energy transfer.

Process of Sheave Pulley

The mold is used to shape the sheave pulley according to the desired design and specifications.


The molten material is poured into the mold to create the sheave pulley’s shape and structure.

Raw Materials

High-quality raw materials such as nylon are used to ensure durability and performance.


The sheave pulleys are manufactured using precise techniques to meet industry standards.


Each sheave pulley undergoes rigorous testing to ensure quality and performance before being released.

Antirust Treatment

Special coatings or treatments are applied to prevent corrosion and increase longevity.

Separate Inspection

Each sheave pulley is individually inspected to guarantee consistency and quality.


Identification marks or labels are added to the sheave pulleys for easy recognition and tracking.

How do you adjust sheave pulleys?

1. Loosen the Set Screw

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

2. Adjust the Position

Move the sheave along the shaft to the desired position for proper tension and alignment.

3. Tighten the Set Screw

Once adjusted, securely tighten the set screw to lock the sheave in place.

4. Test the Operation

After adjustment, test the sheave pulley to ensure smooth and efficient operation.

5. Fine-Tune as Needed

If further adjustment is required, repeat the process until the desired performance is achieved.

6. Regular Maintenance

Perform regular checks and maintenance to keep the sheave pulleys in optimal condition.
