In addition to belts manufactured to ARPM (Association for Rubber Products Manufacturers) standards, Bando produces belts to European standard DIN 7753 and ISO4184. These standards are based on the metric system of measure and have different cross section designations. The Narrow Wedge profile allows for higher speed ratios, shorter center distances, and more compact drives. They are direct replacements for belts on imported machinery and on domestic equipment for export.
