5 Sheave Pulleys

  1. High-quality materials
  2. Precision engineering
  3. Smooth operation
  4. Durable construction
  5. Wide range of applications

Types of Sheave Pulleys

1. Fixed Pulleys

Fixed pulleys have a stationary axle and are used to redirect the force in a lifting system.

2. Movable Pulleys

Movable pulleys have an axle that can move, making it easier to lift heavy loads with less effort.

3. Compound Pulleys

Compound pulleys combine both fixed and movable pulleys to provide a mechanical advantage when lifting heavy objects.

4. Block and Tackle Pulleys

Block and tackle pulleys use multiple pulleys in a system to further increase the mechanical advantage for lifting.

5. Snatch Blocks

Snatch blocks are pulleys that can be attached to a load in the middle of a rope, allowing for directional changes in lifting.

6. Timing Belt Pulleys

Timing belt pulleys are specially designed for synchronous power transmission, commonly used in automotive engines and other machinery.

What is a sheave on a pulley

  1. A sheave is a wheel or pulley with a grooved rim around which a belt or rope runs.
  2. It is designed to change the direction of a force or transmit rotational motion efficiently.
  3. Sheaves can be made of various materials such as steel, aluminum, or plastic.
  4. They are often used in conjunction with belts or ropes to lift or move heavy loads.
  5. Sheaves come in different sizes and configurations to suit specific applications.

What are sheaves used for?

  1. Sheaves are used to increase the mechanical advantage in lifting systems.
  2. They are essential components in pulley systems for various industries such as construction, manufacturing, and transportation.
  3. Sheaves help to reduce the amount of force required to lift heavy objects.
  4. They are also used in power transmission systems to transfer motion between rotating shafts.

The mold is prepared according to the design specifications for the sheave pulley.


The molten metal is 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 the durability and performance of the sheave pulley.


The sheave pulley is manufactured using precision engineering techniques to meet industry standards.


Each sheave pulley undergoes rigorous testing to ensure quality and reliability before being used in applications.

Antirust Treatment

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

Separate Inspection

Each sheave pulley is individually inspected to guarantee that it meets the required specifications and standards.


Finally, the sheave pulley is marked with identification labels for traceability and quality control purposes.

How do you adjust sheave pulleys?

  1. Ensure the pulley system is turned off and disconnected from any power source.
  2. Loosen the set screws or bolts holding the sheave in place.
  3. Adjust the position of the sheave along the shaft to achieve the desired tension on the belt or rope.
  4. Secure the sheave in place by tightening the set screws or bolts.
  5. Check the alignment of the sheave with other pulleys in the system to prevent misalignment issues.
  6. Turn on the pulley system and test the adjustments for smooth operation.
  7. Regularly inspect and maintain the sheave pulleys to ensure optimal performance and longevity.
