Common Symptoms

  • Belt slips, squeals or overheats under load
  • Driven equipment runs slowly or inconsistently
  • Black belt dust appears around the sheaves
  • Belt is cracked, glazed, stretched or frayed

Check Before Replacing

  • Confirm the classical C-section profile and complete original marking
  • Identify whether the old specification uses inside, datum or outside length
  • Inspect sheaves for wear, rust, glazing and groove damage
  • Check shaft alignment, bearings and required tension
Pro Tip: Large-section belts place substantial load on bearings and shafts. Excessive tension can shorten bearing life, while insufficient tension causes heat and slip.

Installation Notes

  1. Disconnect and lock out electrical power.
  2. Relieve belt tension according to the equipment service manual.
  3. Inspect and clean the sheaves before installation.
  4. Install without prying, align the sheaves and tension to specification.
  5. Rotate the drive by hand, reinstall guards, restore power and test operation.
