SynchroChain Timing Belt Construction

The SynchroChain urethane timing belt incorporates a newly developed CTD timing belt tooth profile which is 100% compatible with the Gates® PolyChain GT® timing belt tooth profile. This allows for direct replacement of a Gates® PolyChain GT timing belt. The SynchroChain timing belt also features premium material usage and construction ensuring reliable mechanical power transmission for high torques and for high dynamic stressing. As the first timing belt of this high-performance class it permits reverse flexing in multi timing belt pulley drives and is the optimum alternative to chain drives and the Gates® PolyChain GT timing belt.

The newly developed CTD timing belt tooth profile ensures faultless meshing and hence smooth running at high speeds. At the same time it prevents tooth ratcheting at high torques. The SynchroChain urethane timing belt is well able to cope with a wide range of requirements. It is suitable for new drive designs and at the same time also compatible for use in existing Gates® PolyChain GT® timing belt systems. 

Timing Belt Profiles and Timing Belt Pitches (Currently Available)

  • 8mm CTD (PolyChain GT)
  • 14mm CTD (PolyChain GT)
CTD timing belt tooth profile is interchangeable with the Gates PolyChain GT® timing belt tooth profile


  • Oil-resistant and unaffected by tropical climates
  • Designed for high dynamic stressing up to 40 m/s
  • Maintenance-free
  • Suitable for temperatures from -40 °C to 100 °C
  • Withstands reverse flexing
  • Very hard-wearing

Areas of Application

The SynchroChain timing belt has been developed for punishing heavy duty applications where large power outputs, high torques and high speeds have to be reliably transmitted. The SynchroChain urethane timing belt also excels in applications with high dynamic stressing. The possible applications are nearly unlimited and because of the resistance against wetness, aggressive cleaners and fluctuation of temperature they vary from food industry, mining, harbor terminals to amusement park rides.
