What is a sheave on a pulley?

  • A sheave on a pulley is a wheel with a grooved rim that is used to guide a rope or belt and change the direction of a force.
  • It helps to support and guide the movement of ropes, cables, or belts in various mechanical systems.
  • The sheave’s groove provides a secure grip on the rope or belt to prevent slipping during operation.
  • Sheaves are commonly used in pulley systems to increase mechanical advantage and redirect forces.
  • They come in various sizes and materials to suit different applications and load requirements.

What are sheaves used for?

  • Sheaves are used to change the direction of a force or transmit power in mechanical systems.
  • They help support and guide ropes, cables, or belts in lifting, pulling, or conveying applications.
  • Sheaves are essential components in pulley systems for lifting heavy loads with minimal effort.
  • They are utilized in industrial machinery, construction equipment, and transportation systems.
  • Sheaves play a crucial role in maintaining tension and alignment in various mechanical systems.
  • They are also used in steering systems, elevators, cranes, and other applications that require force transmission.

Process of Sheave Pulley

The mold is created based on the specifications of the sheave pulley design.


The molten raw materials are poured into the mold to form the sheave pulley shape.

Raw Materials:

High-quality raw materials such as polyamide are used to ensure durability and performance.


The sheave pulleys are manufactured with precision and quality control measures in place.


Each sheave pulley undergoes rigorous testing to ensure reliability and performance.

Antirust Treatment:

A special treatment is applied to protect the sheave pulley from corrosion and rust.

Separate Inspection:

Individual inspection is conducted to guarantee the quality and functionality of each sheave pulley.


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

How do you adjust sheave pulleys?

  • Use a sheave alignment tool to check and correct alignment between the sheaves.
  • Adjust the tension of the belt or rope to ensure proper engagement with the sheave pulleys.
  • Inspect and replace worn or damaged sheave pulleys to maintain optimal performance.
  • Regularly lubricate the sheave pulleys to reduce friction and wear on the ropes or belts.
  • Monitor the operating conditions and temperature to prevent overheating and premature failure.
  • Consult the manufacturer’s guidelines for specific instructions on adjusting sheave pulleys.
  • Seek professional assistance if you encounter difficulties in adjusting or maintaining sheave pulleys.
