Types of Sheave Pulleys

1. Fixed Sheave Pulleys

Fixed sheave pulleys have a stationary axle and are commonly used in applications where the load does not need to be adjusted.

2. Movable Sheave Pulleys

Movable sheave pulleys have a movable axle, allowing for adjustments to the load. They are often used in systems that require variable speeds.

3. Compound Sheave Pulleys

Compound sheave pulleys combine multiple sheaves on a single shaft, providing increased mechanical advantage for lifting heavier loads.

4. Snatch Sheave Pulleys

Snatch sheave pulleys have a side plate that allows the rope to be easily inserted and removed, making them ideal for quick and efficient rigging.

5. Wire Rope Sheave Pulleys

Wire rope sheave pulleys are specifically designed to accommodate wire ropes, providing smooth and efficient operation for lifting heavy loads.

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 applied to the belt or rope.

2. Function

Sheaves are used to transmit power, lift loads, and apply tension to belts or ropes in various mechanical systems.

3. Components

A sheave typically consists of a grooved wheel mounted on an axle or shaft, with bearings to facilitate rotation.

4. Materials

Sheaves are commonly made from materials such as steel, aluminum, or plastic, depending on the application requirements.

5. Design

Sheaves are designed with grooves to accommodate belts or ropes, ensuring proper alignment and efficient power transmission.

What are Sheaves Used For?

1. Lifting Heavy Loads

Sheaves are used in lifting systems to increase mechanical advantage and facilitate the lifting of heavy loads.

2. Transmitting Power

Sheaves transmit power from one rotating shaft to another, allowing for the operation of various mechanical systems.

3. Changing Direction of Force

Sheaves change the direction of a force applied to a belt or rope, enabling the movement of objects in different directions.

4. Tensioning Belts or Ropes

Sheaves apply tension to belts or ropes, ensuring proper operation and preventing slipping or loss of power.

5. Controlling Speed

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

6. Supporting Various Applications

Sheaves are utilized in a wide range of industries and applications, including manufacturing, construction, and transportation.

Process of Sheave Pulley

The sheave pulley is manufactured with precision and attention to detail to meet quality standards.


Each sheave pulley undergoes rigorous testing to ensure functionality and safety.

Antirust Treatment

The sheave pulley is treated with anti-rust coatings to prolong its lifespan and maintain performance.

Separate Inspection

Individual inspection is conducted to check for any defects or imperfections before packaging.


Each sheave pulley is marked with relevant information for identification and traceability.

How do you adjust Sheave Pulleys?

1. Loosen the Set Screw

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

2. Slide the Sheave Along the Shaft

Move the sheave along the shaft to the desired position for proper tensioning or alignment.

3. Realign the Sheave

Ensure the sheave is properly aligned with other components for smooth operation.

4. Tighten the Set Screw

Once adjustments are made, tighten the set screw to secure the sheave in place.

5. Check for Proper Functionality

Test the sheave pulley to ensure it operates correctly after adjustments have been completed.

6. Make Further Adjustments if Necessary

If the sheave pulley does not function as intended, repeat the adjustment process until optimal performance is achieved.
