HY-T® Torque Team® classical belts are built with strong Vytacord® tension members. This provides the high-strength, high-horsepower rating capacity needed to effectively transmit drive power. Vytacord® tension members are tough enough to tolerate the misalignment that quickly destroys belts. The Vytacord® material has a very good dimensional stability. Drive performance is consistent, reliable and predictable over the life of the belt. We then add a tough oil and abrasion resistant fabric backing to provide maximum longitudinal flexibility and lateral strength to withstand the dynamic forces acting within a joined belt. The backing also has special adhesion characteristics that enable it to bond inseparably to the V-sections to maintain the unitary integrity of the belt. The cushion in both envelope and cut-edge construction is fiber-loaded. Cut-edge constructions have a fiber-loaded, latest-technology compound that contributes heat and oil resistance and strength.
