SilentSync® is the next generation in synchronous belt technology. This unique, state-of-the-art alternative to straight-tooth belts and drive chains has been enhanced to improve the overall performance of your drive design and helps you save energy. SilentSync® helical offset tooth (H.O.T.) design offers continuous rolling tooth engagement, ensuring a much quieter synchronous drive with reduced vibration and decreases operating noise by as much as 19 dB versus other synchronous systems. SilentSync® belts and flangeless sprockets provide a reduced weight, more compact drive with efficiencies of up to 98%. SilentSync®'s increased horsepower capacity, up to 25% improvement, has the ability to handle an even wider variety of applications. If your application is high heat, SilentSync® can perform continuous at 200 °F. Durability starts with the SilentSync® belt's rubber compound, a cross-linked elastomer formulated to resist tooth deformity and increase tooth rigidity. SilentSync® is also chemically stable to resist the effects of oils, coolants, heat and ozone. SilentSync® high-strength aramid tensile member provides optimal resistance to flex-fatigue, elongation and shock loads while operating at high torque conditions. The facing of SilentSync® belts also reduce tooth engagement friction while standing up to oil and chemical permeation.
