Conti®V Multirib (Poly V)

New names for industrial drive belts

We are aligning and enhancing our industrial drive belt portfolio with a globally consistent naming structure. That is why you will see some changes on our product pages in the next months.


The Conti®V Multirib (formerly, 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 Conti®V Multirib belt the superior choice.

To distribute the drive load evenly across the full width of the sheave, the Multirib belt is built as a single unit with a completely supported, uninterrupted tension member. There are no matching issues. 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 it can handle speed ratios up to 40:1.

With all this capacity, the Conti®V Multirib 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.
