SynchroForce Extreme Timing Belt Construction

Incorporating completely new material compounding, the latest timing belts of the SynchroForce heavy duty series pave the way for economic drive solutions, particularly in the transmission of high power outputs and torques. Excellent tooth stability and resistance to wear ensure a very long service life, making the belts suitable for heavy duty applications beyond the capability of earlier belt generations, while retaining the well-proven benefits of SynchroForce rubber timing belts.

SynchroForce EXTREME timing belts ensures the reliable and continuous transmission of high torques at moderately low belt speeds up to 40 m/s (7,874 ft/min). The new material compounding ensures outstanding tooth stability and sustained tear strength. The multilayer treated cover fabric ensures high abrasion resistance even after long use. Thanks to the modified NBR embedding compound and the heavy-duty aramid tensile member, the belt has a very high resistance to extension, especially in the lower torque range.
