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 protective coating is applied to prevent corrosion and increase longevity.

Seperate Inspection

Each sheave pulley is individually inspected to meet quality standards.


Proper labeling and marking are done for easy identification and traceability.

How do you adjust sheave pulleys?

  • Identify the sheave pulley that needs adjustment.
  • Loosen the set screws on the hub of the sheave pulley.
  • Adjust the position of the sheave pulley on the shaft to the desired location.
  • Ensure proper alignment with other components in the system.
  • Retighten the set screws securely to hold the sheave pulley in place.
  • Check the tension of the belt or rope to confirm proper adjustment.
  • Test the system to ensure smooth operation after the adjustment.
