Poly-V belts / Ribbed belts

What is a poly-v belt?

The Poly-V Belt, or Ribbed Belt has longitudinal v-shaped ribs running along the inside of the belt. These ribs provide a larger contact area, increasing friction force between the pulley and the belt. This enables the belt to transmit more power when compared to an identically sized flat belt or rubber v-belt.

The compact nature of the Poly-V belt makes it ideal for high speed drives which are limited in terms of space. These belts also have a high level of efficiency, reducing the amount of energy that is lost within the drive.
