MasterDrive 5V800

5V800 Narrow V-belt is a narrow profile belt that transfers loads very efficiently and delivers higher horsepower ratings than classical section belts. Its efficient design, executed with premium quality materials and advanced manufacturing techniques, can transmit up to 3 times higher horsepower than classical section belts in the same space or the same horsepower in 1/2 to 2/3 less space. You save belt, sheave weight, space and, of course, cost! Extra strong polyester tensile cords are treated for fatigue and stretch resistance. These rugged cords are the secret to the belt's exceptional length stability and drive uniformity. Cut on a special bias angle, the rubber impregnated fabric cover permits the belt to bend easily around sheaves, reducing stress and the resulting heat build up that shortens belt life. The belt's inner components are protected against dirt, oil and heat by the long wearing cover. Insulation section provides cord support and protection, while bonding the tensile cords to the upper and lower components for the longest possible belt life. The compression section, which is firm enough to maintain cross section uniformity and at the same time flexible enough to reduce heat build up, transfers the load from the tensile cord to the sheave.
