The base compound consists of a polychloroprene rubber compound with fibers inlaid transversely to the running direction. The high-quality and extremely low-stretch polyester or aramid tension cord is embedded in a cushion compound. It is reinforced with a fabric outer surface, and the transverse fibers incorporated provide transverse rigidity without sacrificing flexibility.
optibelt VARIO POWER variable speed belts are the preferred choice for infinitely variable speed control. The special belt structure allows high dynamic loads, superior power transmission capability, and good control characteristics.
Also available as a double-sided belt.
