Continental Conti Synchrochain Carbon Timing Belts
Conti Synchrochain Carbon timing belts from Continental are engineered for industrial drive systems that demand maximum power transmission, high torque capacity, and long service life. Designed for OEMs, machine builders, and industrial end users, these polyurethane timing belts deliver exceptional reliability, efficiency, and stability—especially in dynamic or heavy-load environments. Their carbon tension member ensures minimal stretch, high stiffness, and outstanding durability, making them ideal for modern high-performance machinery.
Advantages and Features
- Up to 5× higher power transmission compared to conventional timing belts at identical width.
- Up to 30% higher power rating versus previous Synchrochain versions.
- Carbon tension member with 50% lower stretch compared to aramid, ensuring maximum dimensional stability.
- Service life increased by up to 100% due to extremely wear- and abrasion-resistant materials.
- Maintenance-free operation and negligible initial tension losses.
- Temperature resistant from −55°C to +80°C depending on application.
- Resistant to oils, grease, fuels, aging, ozone, and tropical environments.
- Belt speeds up to 40 m/s possible.
- Excellent protection against tooth skipping at high loads due to CTD profile.
Typical Applications
Conti Synchrochain Carbon belts are suited for demanding industrial and mobile machinery applications such as:
- Energy recovery systems
- Agricultural machinery
- Woodworking machines
- Printing and packaging machines
- Textile machinery
- Machine tools
These belts are suitable for both OEM drive design and retrofit/replacement applications.

FAQ
What makes the carbon tension member superior to aramid?
The carbon tension member has 50% lower stretch, significantly higher stiffness, and delivers minimal initial tension loss throughout the belt’s lifetime, enabling higher torque transmission and increased efficiency.
What is the advantage of the CTD profile?
The CTD profile merges the positive characteristics of HTD and STD profiles, achieving smoother tooth engagement at high speeds and excellent protection against tooth skipping under high torque.
Can the belt operate in harsh or tropical environments?
Yes. The belt is resistant to aging, ozone, oils, grease, fuel, and tropical climates, making it suitable for demanding industrial environments.
Do Conti Synchrochain Carbon belts require maintenance?
No. They are designed to operate maintenance-free due to extremely wear-resistant materials and stable tension over their entire service life.
What is the recommended tensioning setup?
Inside tensioning pulleys are preferred because they avoid reverse bending. They should be positioned on the slack side close to the large pulley to maintain optimal wrap on the small pulley.
