The sheave pulley design is created and a mold is formed for production.


The molten raw material is poured into the mold to create the sheave pulley shape.

Raw Materials

High-quality materials such as steel or nylon are used to ensure durability.


The sheave pulleys are manufactured with precision and attention to detail.


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

Antirust Treatment

A special treatment is applied to prevent rust and corrosion on the sheave pulley.

Separate Inspection

Individual inspection is conducted to guarantee the sheave pulley meets standards.


Each sheave pulley is marked with essential information for identification.

How do you adjust sheave pulleys?

  • Loosen the set screws
  • Adjust the sheave position
  • Tighten the set screws
  • Check alignment and tension
  • Ensure proper belt or rope tracking
  • Test the system for smooth operation
  • Regularly inspect and maintain sheave pulleys
