Product Description

Product Description

    Self-tooth-forming chains (P.I.V chains) are core transmission parts specially for P.I.V infinitely variable speed variators. The slidable steel slats fit pulley grooves adaptively to realize slip-free continuous stepless speed regulation. Made of heat-treated high-strength alloy steel, they feature high transmission efficiency and outstanding wear resistance, widely applied to textile, printing, packaging, paper-making and other precision variable-speed machinery.
