Protorque® Poly-V Ribbed Belts

Protorque® Poly-V Ribbed Belts are engineered for high-performance power transmission. They offer flexibility, strength, and reliable grip across multiple grooves within a pulley system. These belts are commonly used in applications that demand high-speed transmission and smooth operation across several pulleys, including automotive engines, industrial machinery, and household appliances.

What are the benefits of choosing Protorque poly-v ribbed belts?

ProTorque poly-v ribbed belts showcase longitudinal v-shaped ribs on the inside of the belt, which increase the contact area between the belt and pulley.

This increases the co-efficient of friction, reducing the chance of belt slippage and meaning that the belt is able to transmit more power than an identically sized flat or v-belt. This allows the belt to be used in 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.

What are Protorque® Poly‑V ribbed belts?

Protorque® Poly‑V ribbed belts (also called multi‑rib or micro‑V belts) are flat belts with multiple longitudinal ribs on the inner side. The ribs engage with matching grooves in the pulley to provide high power transmission with low noise and compact drive design.
