What is a Sheave on a Pulley:

  • A sheave on a pulley is a grooved wheel or pulley that holds a belt, rope, or cable to enable movement and power transmission.
  • It helps change the direction of the force applied and allows for the transfer of power between the input and output shafts.
  • The design of the sheave ensures proper alignment and tension for efficient operation.
  • Sheaves come in various sizes and materials to suit different applications and load requirements.
  • They play a crucial role in the smooth and reliable operation of machinery and equipment.

What are Sheaves used for?

1. Power Transmission:

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

2. Load Distribution:

Sheaves help distribute the load evenly across multiple belts or ropes, reducing wear and improving efficiency.

3. Directional Changes:

Sheaves facilitate changes in the direction of force applied, allowing for versatile applications in various industries.

4. Tension Control:

Sheaves assist in maintaining proper tension in belts and ropes, ensuring smooth operation and preventing slippage.

5. Speed Control:

Sheaves can be adjusted to change the speed ratio between input and output shafts, providing flexibility in operation.

6. Lifting and Hoisting:

Sheaves are essential components in lifting and hoisting systems, enabling the smooth and efficient movement of loads.

Process of Sheave Pulley:


The mold for sheave pulleys is carefully designed to ensure accurate dimensions and smooth surfaces.

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

Raw Materials:

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


The sheave pulley is manufactured using precision techniques to meet quality standards and specifications.


Each sheave pulley undergoes rigorous testing to ensure it meets performance and safety requirements.

Antirust Treatment:

The sheave pulley is treated with anti-rust coatings to enhance longevity and protect against corrosion.

Separate Inspection:

Every sheave pulley is individually inspected to guarantee quality and consistency in production.


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

How do you adjust Sheave Pulleys?

1. Determine the Correct Belt Tension:

Ensure the belt tension is within the recommended range to prevent slippage and excessive wear.

2. Use Proper Tools:
