Bonfiglioli HDP, HDO & HF Heavy Duty Gear Units

Overview

Bonfiglioli's heavy duty industrial range covers the high-torque drives behind mining, mineral processing, pulp and paper and bulk handling. The HDP parallel-shaft and HDO right-angle series run from 5,190 to 210,000 Nm, with shrink disc, drywell, taconite seal and forced lubrication options for dusty, wet and remote sites. The HF Series is designed for hoists and overhead cranes.

Gordon Russell supplies the full Bonfiglioli industrial range and matches each gear unit to the motor, coupling, brake and drive it works with. When a drive needs more torque in less space, look at the Bonfiglioli 300M planetary series, which we build in our own shop, up to 2,000,000 Nm.

Frequently Asked Questions

What is the difference between the HDP and HDO Series?

The HDP is a parallel-shaft unit (5,190 to 210,000 Nm, ratios 7.1 to 500). The HDO is a right-angle unit (8,990 to 209,000 Nm, ratios 5.6 to 490). The choice usually comes down to drive layout: HDP when the motor sits in line with the driven shaft, HDO when the drive turns through 90 degrees.

Which options suit harsh mining and mill sites?

HDP and HDO units are available with shrink disc outputs, drywell (leak-free vertical output), taconite seals for abrasive dust, and forced lubrication for high thermal loads. Tell us about the site and duty and we will specify the right package.

When should I choose a 300M planetary instead?

When you need more torque than the HDP or HDO offers, or the drive has to be compact and light. The Bonfiglioli 300M goes up to 2,000,000 Nm, and Gordon Russell builds it in our own shop as a Bonfiglioli 300 Series build centre. See the 300M Series.

Can an HDP or HDO replace a gearbox from another manufacturer?

Often, yes. Send us the nameplate and photos of the existing unit. We compare footprint, shaft heights, shafts and ratings, and if a standard unit will not fit we can supply a drop-in replacement built to your existing dimensions.

Do you rebuild heavy duty gearboxes?

Yes. Our shop rebuilds most gearbox brands and sizes, including teardown, inspection and repair, with emergency service for critical equipment.
