Bonfiglioli worm gears are milestones for the industry worldwide. They succeeded in combining uncompromising quality with state-of-the-art technology and renown price effectiveness.
Absolute flexibility is given by the wide choice of several mounting options, shaft configurations and motor interface, all offered as standard. The helical-worm and the double-worm version, with or without the torque limiter, also add up, creating a highly versatile drive system.
