Kevlar Wedge Banded V-belts are constructed for the most severe conditions. This belt provides extraordinary horsepower capacity along with extreme strength. With less than 1/3 the stretch of polyester corded v-belts, you can be assured that your Kevlar banded v-belt will maintain optimal power transmission. The banded design allows for even load distribution when the machine encounters shock load or pulsation. All Kevlar v-belts are heat and oil resistant and meet or exceed the Rubber Manufacturers Association quality standards.
