Bonfiglioli transmission | 300 Series Planetary drives

The powerful solution to all heavy duty drive problems

Compact, and yet extremely powerful, are the units of the 300 series. Their planetary drive train makes them the ideal choice for all the severe duty applications where shock loadings and impacts are more the rule than the exception. The product configuration is highly versatile, due to several options as far as the mounting, the gear layout, the output shaft and the motor interface. All the features are available for each of the 16 finely spaced frame sizes, spanning over the 1.000 – 450.000 Nm torque range. Finding the perfect match to any drive problem is therefore more than a wish, it is something users can safely rely on – always.
