CONTI SILENTSYNC Self-Tracking Timing Belts
CONTI SILENTSYNC belts are self-tracking heavy-duty timing belts with helical offset teeth made for very quiet and reduced vibration operation.They are manufactured according to ISO 9563.
They offer a powerful innovation in synchronous drive systems: up to 25% higher transmitted power and especially up to 19 dB quieter operation than conventional timing belts. They thus become a possible replacement for chain drives.
Made in USA

Notice
General factory certificates are not sufficient for belts used in potentially explosive atmospheres.
If a test report according to ISO 1813 and ISO 9563 is required for the application, it is necessary to inform us of the request for delivery of belts including the certificate when ordering them (when ordering belts via Eshop, please write this request in the "Note" field before by sending the order). The certificate is issued by ContiTech after the test in the production plant.
