Recommended for use on special drives where space and weight limitations are critical. These “narrow” cross-sections can transmit up to three times the horsepower of the classical cross-sections (A, B, C, and D) in the same amount of drive space. Suitable for all industrial applications, particularly where space, weight and horsepower capacity are critical.

  • Gates Curves provide proper cord support and full contact with the sheave-groove for uniform loading, uniform wear, and increased belt life.
  • 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.
  • The Flex-Weave® Cover is a patented construction for longer cover life, providing extended protection to the core of the belt from oil, dirt, and heat.
  • Meets or exceeds RMA standards for static conductivity and heat and oil resistance.
