Belt Description
HTD 8M-912-50 CONTI SYNCHROFORCE ADVANCE PRO (EPDM, Formerly CXA) is a heavy-duty timing belt designed to deliver top performance in transmitting the highest torque. It is antistatic in compliance with ISO 9563.
The CONTI SYNCHROFORCE ADVANCE PRO belts are made of an aramid-fiber reinforced EPDM rubber, providing exceptional temperature resistance, with an aramid-cord tension member. They offer a significantly extended service life compared to the previous chloroprene generation (in the ContiTech portfolio, they replace the former CONTI SYNCHROFORCE CXA series).
Construction
- Protective low-friction polyamide fabric
- Teeth made of aramid-fiber reinforced EPDM rubber
- Aramid-cord tension member
- Backing made of aramid-fiber reinforced EPDM rubber
Typical Applications
CONTI SYNCHROFORCE ADVANCE PRO timing belts in the H8M profile are intended for heavily loaded industrial drives with the highest torque requirements and high dynamic forces.
They are typically used in highly stressed power transmissions in machine tools, presses, heavy conveyor systems, printing and textile lines, automated production systems, and other machinery with extreme performance demands.
Thanks to the improved temperature resistance provided by the advanced EPDM compound, additional application possibilities open up.
Properties
- High power transmission capability
- Long service life – significantly extended service cycle compared to the previous chloroprene (CR) generation

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.
