The Bonfiglioli range of mechanical speed variators comes with IEC motor adaption and fits between the electric motor and the gearbox. They are used to control speed gearbox input speed via either a manual handwheel, servo or speed gauging kit. All Torque Transmissions represents Bonf

The distinctive feature of mechanical variators lies in their ability to operate up to the limit of permitted torque while avoiding slippage of the drive mechanism that would otherwise dramatically reduce variator life.  When selecting Bonfiglioli variators (known as the ‘V̵
