SilentSync® Drive System

The construction of SilentSync® belts and sprockets makes them extremely adaptable to the needs of design engineers and cost-efficient for the end user

SilentSync® belts and sprockets are a technological breakthrough. A patented Helical Offset Tooth (H.O.T.) design provides continuous rolling tooth engagement, allowing the SilentSync® System to run quieter with less vibration than any other synchronous belt available today.

Product Features

1. Aramid Tensile Member
> Pound for pound, stronger and more flexible than steel to handle today’s drive designs
> Resists fatigue, elongation and shock loads, even in high-torque conditions, so there’s no need to retension belts once properly installed
2. Plioguard® Facing
> New proprietary treatment strengthens the tooth, increading rigidity and load carrying capacity
> Reduces tooth engagement friction, allowing for prolonged belt life and minimal wear
> More tolerant of debris, high temperature, oil and chemical permeation, allowing the belts to operate in a wide variety of environments
3. HiBrex® Rubber Compound
> Resists tooth deformity while increasing tooth rigidity to ensure precise synchronization over prolonged use
> Resists the effects of oils, coolants, heat and ozone for maximum service life
4. SilentSync Sprockets
> Continuous rolling tooth engagement allows belt to enter sprocket with minimal impact, wear and operating noise, thus creating longer-lasting, quieter drives
> Does not require flanges; helical offset tooth design allows belt to self-track
> Over 1,500 sprocket combination available, making it easier to match the desired design speed
> Available in ductile iron, steel, aluminum or stainless steel constructions to meet a variety of design criteria

Application

SilentSync® is more than just a synchronous drive system. With up to 25% more power capacity* and static conductivity,** it is a powerful upgrade to the original SilentSync – and even more advanced than standard round-tooth belts and chain drives. Operating up to 19db quieter than straight-tooth belts, SilentSync’s patented Helical Offset Tooth (H.O.T.) design merges belt and sprocket into the quietest, smoothest and one of the most compact synchronous drive packages available. The result is a continuous rolling tooth engagement that reduces vibration and improves the overall efficiency of your drive system.

By employing circular arc geometry, SilentSync belts and sprockets are able to provide better ratcheting resistance, precise movement, increased horsepower rating and improved stress distribution – all to better withstand the shearing action of high torque loads. In addition, SilentSync sprockets are available in over 1,500 combinations, making it easy to match the range of sizes that are required by your system. More speed ratio options allow for more design flexibility and smaller, lighter drives.

The use of a flangeless sprocket also ensures more compact, lighter drives with precision performance. SilentSync® belts and sprockets come in a wide variety of stock sizes with custom manufactured sizes being available for specialty drive requirements.

A Full Spectrum of Sizes

Color	Yellow	White	Purple	Blue	Green	Orange	Red
Pitch	8mm	8mm	8mm	14mm	14mm	14mm	14mm
Width	16mm	32mm	64mm	35mm	52.5mm	70mm	105mm

The SilentSync Color Spectrum System makes it the easier synchronous drive system to sell, purchase and install. The part numbering system for SilentSync includes a letter that corresponds to the color of the branding on the belt (“Y” for Yellow, “W” for White, etc.). Each color defines a particular tooth pitch and belt width. Match the colors, and you have matched the correct belt and sprocket.
