This Challenge A70 classical A profile V-belt has a top width of 13mm (0.512"), a pitch width of 11mm (0.433"), a section height of 8mm (0.315"), an outside length of 1830mm (72.05"), an inside length of 1780mm (70.08"), and a pitch length of 1810mm (71.26"). It's made of rubber reinforced with polyester cords to minimize stretching and increase tensile strength, and is resistant to heat, oil, and static, making it suitable for rugged operating environments. It has a working temperature range of -22 to +158 degrees F (-30 to +70 degrees C), and complies with International Organization for Standardization (ISO) 4184 for datum lengths; ISO 1813 for anti-static properties; and British Standards (BS) 3790, Deutsches Institut für Normung (DIN) 2215, and Association for Rubber Products Manufacturers (ARPM) IP-20 for quality assurance. This Challenge A70 classical A profile V-belt is suitable for use in a variety of commercial and industrial applications, such as conveyor systems, manufacturing, mining and construction equipment, and agricultural and automotive power transmission, among others.
Traditional classical belts are designed for operating at higher speeds over small diameter pulleys and short-center distances. They can be used in multiple V-belt drives and are used frequently in abusive environments such as farming and manufacturing. They are constructed to withstand the heat of the outdoors and oily, dirt-filled manufacturing environments.
The Challenge Group manufacturers power transmission components, including chains, sprockets, belts, pulleys, shaft couplings, and bearings. The company, headquartered in Wolverhampton, England, meets International Organization for Standardization (ISO) standard 9001.
