ContiTech Poly-V® 20039772 Non-Cogged Banded Belt, J Section, 0.092 in W Top, 49 in L Outside, 0.14 in THK, Polybutadiene

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.
