CONTI SYNCHROFORCE ADVANCE PRO HTD H8M Timing Belts
CONTI SYNCHROFORCE ADVANCE PRO heavy-duty timing belts in the HTD H8M profile are designed to deliver top performance in transmitting the highest torque. They are antistatic in compliance with ISO 9563.
The 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 HTD 8M CONTI SYNCHROFORCE CXA belts).

New EPDM Generation of CONTI SYNCHROFORCE Belts Replacing Chloroprene Rubber (CR) Belts
This represents a major technological step forward, delivering significant improvements in key performance characteristics of drive belts – higher temperature resistance, longer service life, reduced environmental impact, and cleaner operation.
The belts feature a new imprint design which, like the designation of the performance classes, follows the principles defined within the Continental CONTINUITY project.
Production of the previous-generation CONTI SYNCHROFORCE CXA belts was discontinued at the end of 2025. Items currently in stock will continue to be available in our online store while supplies last.
The new CONTI SYNCHROFORCE ADVANCE PRO belts retain exactly the same dimensions (pitch, length, and profile) as their predecessors and can therefore replace them smoothly and without concern.
Belt 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
- Conditionally oil-resistant
- Suitable for use in tropical environments
- Temperature resistance from −40 °C to +120 °C
- Chlorine-free, PFAS-free, with reduced levels of PAHs, halogens, and solvents
- Maintenance-free
- Antistatic properties according to ISO 9563

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.
