Tri-Power® Belts

Constructed with Gates proprietary construction, this belt has a superior combination of flex and load carrying capacity, as well as less stretch resulting in less maintenance.

Suitable for all industrial applications, particularly where small or sub-minimal sheave diameters are required.


  • Notches molded into the belt during manufacturing make this belt well suited for drives with smaller diameter sheaves.

  • Belt Edge is machined for even sheave groove contact resulting in less slip and wear.

  • Flex-Bonded Cords are strongly bonded to the body of the belt resulting in equal load distribution and the absorption of bending stress without cord deterioration.

  • Patented EPDM Material construction provides -60°F to +250°F temperature range to resist belt cracking.

  • Meets RMA oil and heat resistant standards.

  • Meets RMA static conductivity requirements.
