Polyflex® JB® Belts


Joined belt construction provides increased belt stability, preventing belts from turning over or from coming off drive.

Unique 60° angle polyurethane construction transmits greater loads at higher speeds in less space than conventional V-belts.

Markets/Applications
Use in place of Polyflex singles on drives requiring joined sets. A partial listing of applications includes machine tools, computer peripherals, medical equipment, library equipment, small appliances, blower drives and dough mixers.

Features/Advantages

  • High Modulus Polyurethane compound resists fatigue, wear, ozone, and most environmental conditions.

  • Precise casting method eliminates layers and overlaps for smooth running and low vibration.

  • Ribbed backing provides greater lateral stability and relieves bending stress.

  • Working temperature range: -65°F to +180°F (-54°C to +85°C).

  • Joined belt construction provides high stability, preventing belts from turning over or coming off of the drive.
