1. Definition

A sheave on a pulley is a grooved wheel or pulley that holds a belt, wire rope, or chain to transmit power and change the direction of the force applied.

2. Function

The main function of a sheave on a pulley is to guide and support the belt, wire rope, or chain, ensuring smooth and efficient power transmission.

3. Materials

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

4. Design

Sheaves on pulleys are designed with grooves or channels to accommodate the specific type of belt, wire rope, or chain being used for power transmission.

5. Installation

Proper installation of sheaves on pulleys is crucial to ensure smooth operation and prevent premature wear and tear on the components.

What are Sheaves Used For?

1. Power Transmission

Sheaves are used to transmit power from one rotating shaft to another using belts, chains, or wire ropes.

2. Direction Change

Sheaves are used to change the direction of the force applied by redirecting the motion of the belt, chain, or wire rope.

3. Tensioning

Sheaves are used to maintain proper tension in the belt, chain, or wire rope to prevent slippage or excessive wear.

4. Speed Control

Sheaves can be used in conjunction with variable speed pulleys to control the speed of machinery or equipment.

5. Load Distribution

Sheaves help in distributing the load evenly across the belt, chain, or wire rope, reducing stress on individual components.

6. Noise Reduction

Properly designed sheaves can help in reducing noise during the operation of machinery or equipment.

Process of Sheave Pulley

The mold for sheave pulleys is created based on the design specifications of the product.


The molten metal is poured into the mold to form the shape of the sheave pulley.

Raw Materials

High-quality raw materials are used to ensure the durability and performance of the sheave pulley.


The sheave pulley is manufactured using precision machining and quality control processes.


Each sheave pulley undergoes rigorous testing to ensure it meets the required standards and specifications.

Antirust Treatment

The sheave pulley is treated with anti-rust coatings to protect it from corrosion and prolong its lifespan.

Separate Inspection

Each sheave pulley is individually inspected to check for any defects or imperfections before final assembly.


After passing inspection, the sheave pulley is marked with identification codes for traceability and quality control purposes.

How do you adjust sheave pulleys?

1. Tension Adjustment

Adjust the tension of the belt, chain, or wire rope to ensure proper alignment and performance.

2. Alignment Adjustment

Check and adjust the alignment of the sheave pulleys to prevent excessive wear and noise.

3. Lubrication

Apply lubrication to the sheave pulleys to reduce friction and ensure smooth operation.

4. Inspection

Regularly inspect the sheave pulleys for wear, damage, or misalignment and make necessary adjustments.

5. Cleaning

Clean the sheave pulleys regularly to remove dirt, debris, or build-up that may affect their performance.

6. Professional Maintenance

Seek professional help for adjusting sheave pulleys if you are unsure or if there are complex issues that need to be addressed.
