The molten raw materials are poured into the mold to create the pulley.

Raw Materials:

High-quality materials are used to ensure durability and performance.


The pulleys are manufactured with precision and attention to detail.


Each pulley undergoes rigorous testing to ensure quality and performance.

Antirust Treatment:

The pulleys are treated to prevent rust and corrosion.

Separate Inspection:

Each pulley is individually inspected for quality control.


Final markings are added for identification and traceability.

Should I replace belt tensioner or just pulley?

  1. If the tensioner is failing, it is recommended to replace the entire assembly.
  2. Replacing only the pulley may not address the root cause of the issue.
  3. It is more cost-effective in the long run to replace the entire tensioner assembly.
  4. Ensure proper installation and maintenance to prevent future issues.
  5. Consult a professional mechanic for proper diagnosis and replacement.

How does a belt tensioner pulley work?

  1. The pulley rotates to adjust the tension on the belt.
  2. It maintains the proper tension required for smooth operation.
  3. Ensures the belt stays in place and does not slip or misalign.
  4. Works in conjunction with other engine components to optimize performance.
  5. Plays a crucial role in the overall function of the engine.
