Bonfiglioli combined gearboxes combine the high technology, performance and efficiency of planetary gearboxes with the robustness, quality and reliability of bevel helical gearboxes. These planetary/bevel helical combination gear boxes deliver the high transmissible torque of Bonfiglioli planetary 300 Series along with the excellent power transmission characteristics of bevel helical HDO Series and are ideal for applications that demand high power density along with medium-low output speeds.

The 3/H range consists of 10 standard catalogue sizes that can transmit up to 1200 kNm of torque. Custom combinations are also available. A wide choice of gear ratios and above all the availability of numerous intermediate sizes enable the 3/H range to offer a truly complete answer to the needs of target heavy duty applications.
