More grip. Less slip. The Power-Wedge® Cog-Belt® combines the advantages of the narrow wedge design with raw edge performance for maximum operating efficiency in a compact drive package. The narrow profile permits reduced drive widths and a smaller drive envelope. Higher horsepower ratings translate into greater design flexibility - reducing drive cost, space and weight. The Power-Wedge® Cog-Belt® is now made of EPDM (ethylene propylene diene monomer), a synthetic rubber with outstanding properties. The raw edge construction contributes to outstanding operating efficiency. More torque with little or no slippage. The result is savings - in time, in belt life and in energy costs.
