The Poly-V® belt is a single, endless belt with longitudinal V-shaped ribs that mate consistently with the V-grooves in the sheaves. It combines the convenience of a thin, one-piece flat belt with the strong gripping traction of multiple V-belts to make the Poly-V belt far better than either for many applications. To distribute the drive load evenly across the full width of the sheave, the Poly-V belt is built as a single unit with a completely supported, uninterrupted tension member. There is no matching problem. No separate belts to turn over, grab, slip or interfere with each other. The thin cross-section profile allows use of smaller pulleys than standard V-belts and Poly-V belts handle speed ratios of 40:1. With all this capacity, the Poly-V belt tracks properly without special guides, flanges, crowns or deep grooves. And it resists seating in the grooves, so speed ratios remain more consistent and output speed remains more uniform.

Poly-V Belt Advantages
  • Increased belt and sheave life
  • Reduced drive cost
  • Consistent performance
