Polyflex® Belts

Gates® Polyflex® Belts provide a versatile power transmission solution when space is at a premium. Their unique 60° angle polyurethane construction transmits greater loads at higher speeds in less space than conventional V-belts.

  • Polyurethane is extremely resistant to heat, chemicals and oil
  • Temperature range: -65°F up to 185°F (-54°C up to 85°C)
  • Improves adhesion to the tensile cords

Big Power for Small Spaces

Polyflex™ Belts were specially designed to transmit maximum power for a variety of small precision v-belt drive applications. The belt's ribs are designed to reduce bending stress on miniaturized drive components, while their 60° angle construction provides added support for even load distribution. This enable their use in high-performance, precision applications, accommodating shaft speeds in excess of 10,000 rpm.

Features and Benefits

  • Uniformity is ensured because the polyurethane compound is not layered but cast without overlaps for smooth running and low vibration
  • High Modulus Polyurethane compound (HMPE) resists fatigue, wear, ozone, and most environmental conditions
  • Precision casting eliminates layers and overlaps to enable low vibration operation
  • Ribbed backing provides greater lateral stability and relieves bending stress
  • Custom-made sheaves can be ordered through the Gates MachineWorks team

A Material Difference

Every Gates® power transmission product is made at the leading edge of material science and manufacturing processes. Gates Polyflex™ Belts are precision cast, using our own proprietary process that forms the belt in a seamless, single layer. Their HDPE compound construction provides material properties that combine strength, flexibility, and high temperature tolerance. The result is a precision application belt that provides exceptional load-carrying capacity, application versatility, and durability.
