Jul 12, 2019 - Bonfiglioli 300M Series


Bonfiglioli is introduced its new 300M range of planetary gearboxes in 2017, which have achieved greater torque without increasing the size of the gearbox, to produce greater performance, efficiency, and cost savings for many industries; packaging, bulk materials handling, mining process equipment, food and beverage, materials handling, water treatment and waste handling just to name a few.


The 300M series has eight new sizes from 310M to 318M, all of which have a significant improvement in torque over their preceding models and set new industry benchmarks for torque ratings at one million cycles.


Depending on the size, torque has been improved by up to 45%, as shown in the graphic below.

One of the innovative improvements in the series is the addition of a new bearing design. The 300M series uses a customised roller design with an inner race on the pin and an outer race on the planet gear. This creates a bigger roller diameter, with a higher load capacity and greater torque.


The new 300M series has been engineered to the highest possible standard of quality. The gearboxes are built for reliability, durability and improved performance. A significant advantage of the higher torque capacities are that a smaller size gearbox can do the same task that a much larger one would have had to do previously. This can mean savings in power, space and costs, both up-front and over time.

The 300M series is completely interchangeable with the existing 300 series gearboxes, and no machine modification is required when upgrading to the new units.


Major applications for the 300M series include:

• Mining – car dumpers and stacker reclaimers

• Materials handling – screw conveyors and apron feeders

• Intralogistics– Cranes and winches, jib cranes and ship loaders

• Food and beverage – spiral freezers and flaking machines

• Water and wastewater – mixer agitators and band screeners


Last but not least, we want to mention that Bonfiglioli announced the expansion of its range of helical-bevel gear drives by presenting four new sizes of the proven HDO helical-bevel gear series: 71, 81, 91 and 95 ranging from 9 to 23 kNm torque. The design of the new helical-bevel gear units of the HDO series are modular in design, extremely reliable, and offer high flexibility due to vertical and horizontal symmetry.


Power Transmission is a competitive industry where companies are constantly striving to improve efficiency, minimise downtime and reduce costs. The Bonfiglioli 300M series has been designed with these goals in mind, and the industry-leading torque benchmarks will greatly optimise their performance.
