Variable Speed Belts

Our variable speed belts are made using chloroprene rubber (CR), polyester cord, aramid fiber and Kevlar fiber. We produce all kinds of multi-speed belts used for various types of haulage motors and mechanical equipment in accordance with Chinese standards.


Our high quality variable speed belts have highly efficient power transmission even under high impact, high temperatures, variable transmissions and other harsh conditions. They have been sold in Taiwan, Russia and many other countries and regions in Southeast Asia, Central Europe, South America and Africa.

Variable Speed Belts

The industrial belts are applicable in step-less variable transmission of printing machinery, electrical machinery, rubber machinery, textile machinery, light industrial machinery, woodworking machinery, and food machinery.


We are happy to manufacture variable speed belts with custom specifications according to your designs and samples. If you are interested in our superior transmission belts, please contact us immediately!
