Bando SPA1425 1425 inch long 12.5 inch wide 10 inch high V-Belt 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.. Oil and heat resistant bias cut envelope protects the belts inner components against dirt, oil and heat. Banprene impregnated fabric provides lateral stability while permitting axial flexibility for operating around small pulley diameters. High density polyester tension members treated for fatigue and elongation resistance minimize maintenance costs. Banprene compression section maintains tension member cross section uniformity while remaining flexible enough to reduce heat build up one of the primary causes of premature belt failure.
