Bonfiglioli 300M Series Planetary Gearboxes

Overview

The Bonfiglioli 300M Series is a modular range of heavy-duty planetary gear units covering 20 frame sizes, from the 300 up to the 325. Inline and right-angle versions, foot or flange mounting, and several output shaft and motor-input options let one platform cover a wide range of heavy-duty drives.

As a Bonfiglioli 300 Series build centre, Gordon Russell configures and assembles units locally, which shortens lead times and keeps engineering support close to the site.

Other 300 Series Configurations

The 300M platform is also built in these configurations. Gordon Russell supplies and supports them alongside the 300M.

Bonfiglioli 3/H Series

Planetary units with a helical-bevel input stage for the highest transmissible power in the Bonfiglioli range, 46,660 to 1,188,610 Nm, ratios 30 to 1,160; base plates, fluid couplings and shoe brakes available.

Bonfiglioli 3/A and 3/V Series

Right-angle planetary units: 3/A from 1,250 to 15,680 Nm (ratios 18.7 to 731) and 3/V from 1,250 to 655,740 Nm (ratios 18.7 to 5,234) with high overload capacity.

Combined Units

Bonfiglioli A Series helical-bevel and VF/W worm units combine with the 300 Series for very high reduction ratios.
