SilentSync® offers the following

Aramid Tensile Member – pound for pound, stronger & more flexible than steel to handle today’s drive design. Resists fatigue, elongation and shock loads, even in high-torque conditions, so there’s no need to retension SilentSync® belts once properly installed.

HiBrex® Rubber Compound – resists tooth deformity while increasing tooth rigidity to ensure precise synchronization over prolonged use. Also resists the effects of oils, coolants, heat and ozone for maximum service life.

Plioguard® Facing – proprietary treatment strengthens the tooth, increasing load carrying capacity. Reduces tooth engagement friction, allowing for prolonged belt life and minimal wear while allowing the belts to operate in a wide variety of environments.

Color Spectrum System – color-coded part numbering system of belts and sprockets make it easier to select proper drive combinations. Match the color and you’ve matched the correct belt and sprocket!
