These drive belts are needed to drive our drive models. One bag contains five drive spirals. The spirals are made of spring wire and can be closed by twisting into a belt. The drive belts are available in widths 2 mm and 2.5 mm. The shorter drive spirals are 26 cm long. However, drive spirals in length 50 cm are better suited for the simultaneous operation of several Wilesco models, so that the system can be designed more variable.
