Conti® SilentSync

Powerful, quiet, energy efficient: Thanks to its combination of a helical tooth design, aramid tension member and strong rubber, this belt boasts a wealth of inherent advantages. The SilentSync is self-tracking, has a high power capacity and can withstand high temperatures. This makes it an excellent alternative to both traditional timing belts and V-belts.

Conti® SilentSync: More than just a timing belt

Offering an increase in power transmission of up to 80 % and electrical conductivity*, Conti® SilentSync is a high performance upgrade on standard timing belts. The drive belt is up to 19 dB quieter than straight toothed belts in operation, its Helical Offset Tooth (HOT) design merging belt and sprocket into one of the quietest, smoothest and most compact timing belt drives available. The result is continuous tooth engagement that reduces vibration and improves overall system efficiency.


Thanks to the helical toothing, SilentSync belts and sprockets are able to provide greater resistance to ratcheting, more precise alignment, increased power capacity and improved tension distribution – all to better withstand the shearing action of high performance drives. SilentSync sprockets are additionally available in over 1,500 combinations, making it easy to find a drive configuration that matches your system. The wide range of possible transmission ratios allows for more design flexibility and lighter, more compact drives.
