The teeth are molded from synthetic rubber and then made wear-resistant with a specially treated polyamide fabric. The material offers high strength and dimensional stability and therefore guarantees absolutely synchronous power transmission. Conditional resistance to oil, coolants, heat and ozone are also ensured thanks to the material used.
The tension member consists of an aramid cord. It shows no aging or appreciable elongation, meaning that typically no retensioning is needed.
The belt backing made of the same rubber, though with a polyester fabric, is highly flexible, as a result of which the SILENTSYNC also has no problem with reverse flexing.
The H.O.T. profile (Helical Offset Tooth) incorporates an STD profile with all its benefits and the added advantages of helical tooth design. Self-tracking and lower noise are therefore the characteristic features of this tooth design.

SILENTSYNC is more than just a synchronous drive system. With up to 80% more power capacity and static conductivity,* it is a powerful upgrade to standard synchronous belts.
Operating up to 19 dB quieter than straight-tooth belts, SILENTSYNC’s 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, more precise alignment, increased horsepower rating and improved stress distribution – all to better withstand the shearing action of high-output drives. 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.
