What is a Sheave on a Pulley?

1. Definition

A sheave is a grooved wheel or pulley used with a belt or rope to change the direction or point of application of a force.

2. Function

Sheaves are used to transmit power, support and guide belts or ropes, and provide mechanical advantage in various applications.

3. Components

A sheave consists of a wheel with a groove around its circumference to accommodate the belt or rope.

4. Material

Sheaves are typically made of materials such as steel, cast iron, or aluminum, depending on the application requirements.

5. Types

There are different types of sheaves, such as fixed, adjustable, and variable speed sheaves, each serving specific purposes.

What are Sheaves Used For?

1. Power Transmission

Sheaves are used to transmit power from one component to another through belts or ropes.

2. Belt Tensioning

Sheaves help maintain proper tension on belts, ensuring efficient power transfer and preventing slippage.

3. Speed Control

Sheaves can be used to adjust the speed ratio between the input and output components in mechanical systems.

4. Direction Change

Sheaves change the direction of belts or ropes, allowing for more versatile applications in various industries.

5. Load Support

Sheaves support and guide belts or ropes, distributing the load evenly and reducing wear and tear.

6. Mechanical Advantage

Sheaves provide mechanical advantage by increasing the force or distance of movement in mechanical systems.

Process of Sheave Pulley


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


The molten material is poured into the mold to create the desired shape of the sheave pulley.
