Contitech CTD 1120-8M-21 Timing Belt, 140 Teeth, 21mm Width

The Conti® Synchrochain is a high performing timing belt designed for applications in drives with very high acceleration forces, as well as for the transmission of high torque at low speeds. The combination of extraordinary tensile strength with a high tear resistance making extreme applications possible. It's original design has a newly developed CTD profile with ultra strong aramid tensile members embedded in the compound ensuring reliable power transmission for high torques.

• High dynamic stressing up to 40 m/s
• Polyurethane backing and teeth
• Special treated fabric
• Aramide cord with S/Z twists
• Maintenance free
• No lubricating or retightening required
• Low noise operation
• Highly resistant to various chemicals and oils
• UV and ozone resistant
• Tropicalized
• Temperature resistant from -40°C to 80°C

Conti® Synchrochain timing belt transmits rotary motions at exact angles and a constant belt speed. The match between the belt and drive pulley are synchronous, preventing ratcheting and increasing reliability.
The newly developed CTD profile (Conti Torque Drive) combines the advantages of both the HTD and the STD profile. Ultra smooth running is provided by the arch shaped pulley and the higher tooth ensuring harmonic tooth meshing and excellent protection against belt slip.
