The CONTI SYNCHROBELT® HTD synchronous drive belt offers more than a standard toothed belt. Its designation, HTD = High Torque Drive, stands for the transmission of high torques. It features a completely new tooth-profile design as an advancement of the trapezoidal toothed belt, resulting in a uniform transmission of power when the teeth are in mesh, in a better transfer of belt tension to the tension cord, a uni form distribution of stresses within the tooth itself and, thus, in a minimum tooth deformation.
