CONTI® Dual Hi-Performance Pd® belts can replace two or more single sided synchronous belts, less space is needed. This reduction in space means smaller sprockets can be used, bringing the weight and component cost of the drive system down considerably, contributing to a more efficient drive system. CONTI® Dual Hi-Performance Pd® belts with their unique round tooth profile, drop into corresponding HTD sprockets. They were designed to minimize interference between belt and sprocket during mesh, providing greater horsepower capacity without slippage or speed variation. By designing the tooth to disperse critical stresses and create a positive engagement with the sprocket, belt performance is improved along with assuring longer belt life. The tension carrying member in Hi-Performance Pd® and dual positive drive belts is twisted from multiple strands of fiberglass cord which are high in tensile strength, flex life and resistance to elongation. ContiTech CONTI® Dual Hi-Performance Pd® Drive Belt, Dual Sided Synchronous, 130 Teeth, 8 mm Pitch, 1040 mm Overall Length, 50 mm Width, -50 to 210 °F, Specially Treated Fabric/Synthetic Rubber, Aramid Reinforced
