  • Self-tensioning design: Gates Micro-V Stretch Fit belts are made to fit snugly and work as intended on unique stretch fit drive systems. Gates keeps adding coverage in this growing segment.
  • Cord-locking adhesive: A specially formulated adhesive locks onto the cord. This lets the cord elongate and stretch without losing tension.
  • Polyamide tensile cord: The Gates-engineered advanced polyamide cord combines the strength and flexibility the drive needs.
  • EPDM ribs: The patented, highly engineered EPDM ribs are extremely resistant to contamination, wear and pilling.

Single-use only: Stretch Fit belts must be replaced if removed. Plan on a new belt any time this belt comes off.

Signs this belt may need replacing include squealing or chirping, cracked or glazed ribs, pilling and fraying. Inspect the belt and the related pulleys to confirm the cause before replacing.
