V-ribbed belts combine the high flexibility of a flat belt with the high power of a V-belt. The parallel grooves on the V-section are made of a low-wear rubber compound. The heavy-duty tensile cord is designed for the varied applications of the V-belt. The entire width of the V-ribbed belt is surrounded by a non-slip rubber compound. The wear-resistant rubber provides quiet operation, oil and heat resistance, and long life.
