Overview

• 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.
• 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.
• Resists seating in the grooves, so speed ratios remain more consistent and output speed remains more uniform.
