Types of Sheave Pulleys

1. Fixed Pulleys

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

2. Movable Pulleys

Movable pulleys have a pulley that moves with the load, providing a mechanical advantage when lifting heavy objects.

3. Compound Pulleys

Compound pulleys combine fixed and movable pulleys to provide increased mechanical advantage for lifting.

4. Snatch Blocks

Snatch blocks are versatile pulleys that can be used to change the direction of a cable or increase the pulling capacity.

5. Idler Pulleys

Idler pulleys are used to guide and tension the cable, maintaining proper alignment and tension during operation.

6. Timing Belt Pulleys

Timing belt pulleys are specially designed for synchronous power transmission in machinery and equipment.

What is a sheave on a pulley?

1. Definition

A sheave is a pulley with a grooved wheel used to guide and support a cable or belt.

2. Function

Sheaves help change the direction of a cable, provide a mechanical advantage, and maintain tension during operation.

3. Components

A sheave consists of a wheel with a groove, a shaft or axle, and bearings for smooth rotation.

4. Types

Sheaves come in various types, including single groove, double groove, and multi-groove configurations.

5. Applications

Sheaves are commonly used in lifting and rigging applications, as well as in machinery and equipment for power transmission.

What are sheaves used for?

1. Cable Pulling

Sheaves are used to guide and support cables during pulling operations, reducing friction and wear.

2. Lifting and Rigging

Sheaves are essential components in lifting systems, providing mechanical advantage and changing the direction of force.

3. Power Transmission

Sheaves are used in machinery and equipment for transmitting power between shafts using belts or cables.

4. Tensioning

Sheaves help maintain proper tension in cables or belts, ensuring smooth and efficient operation.

5. Steering

Sheaves are used in steering systems of vehicles and marine vessels to guide and control cables for directional control.

6. Material Handling

Sheaves are employed in material handling equipment for lifting, lowering, and moving heavy loads safely and efficiently.

Process of Sheave Pulley

spa pulley


The mold for sheave pulleys is designed to create the desired shape and dimensions of the pulley.


Raw materials are melted and poured into the mold to form the sheave pulley through the casting process.

Raw Materials

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


The production process involves machining and finishing the sheave pulley to meet the required specifications.


Each sheave pulley undergoes rigorous testing to ensure quality, performance, and safety standards are met.

Antirust Treatment

Sheave pulleys are treated with anti-rust coatings to protect them from corrosion and extend their lifespan.

Separate Inspection

Each sheave pulley is inspected separately to identify any defects or imperfections before final assembly.


Sheave pulleys are marked with essential information such as size, load capacity, and manufacturer details for identification.

How do you adjust sheave pulleys?

1. Tension Adjustment

Adjust the tension of the cable by moving the sheave pulley closer or further from the anchor point.

2. Alignment Adjustment

Align the sheave pulleys to ensure the cable runs smoothly without any deviation or rubbing.

3. Lubrication Adjustment

Apply lubrication to the sheave pulley bearings to reduce friction and improve performance.

4. Load Adjustment

Adjust the load on the sheave pulley to prevent overloading and ensure safe operation.

5. Speed Adjustment

Adjust the rotational speed of the sheave pulley to match the required speed of the application.

6. Maintenance Adjustment

Regular maintenance of the sheave pulleys, including cleaning and inspection, is essential for optimal performance.
