Rossi H Series helical gearbox, manufactured in Italy

The Rossi H Series helical gearbox, manufactured in Italy, is a highly efficient industrial transmission system designed for continuous and precise power transfer in heavy-duty machinery. It features a multi-stage helical gear arrangement with case-hardened and ground gears manufactured to DIN class 6 precision. The output torque reaches up to approximately 18,000 Nm, with mechanical efficiency exceeding 97 percent. The reduction ratio ranges from 3.5 to 400, and its modular design allows flexible installation in foot-mounted or flange-mounted configurations. The housing is made of G300 ductile cast iron with precision machining to minimize vibration and noise. The lubrication system can be splash or forced circulation, depending on load and speed requirements.

The Rossi H Series gearbox incorporates high-load-capacity rolling bearings and heat-resistant seals for long service life. The input and output shafts are coaxial and dynamically balanced for loss-free torque transmission. The operational temperature range is from -25 to +90 degrees Celsius, and the gearbox can be directly coupled with IEC electric motors up to 132 kW. The nominal noise level remains below 70 dB, and the unit weight varies between 150 and 720 kilograms depending on the model. Certified under CE and ISO 9001 standards, the H Series gearbox is ideal for steel, petrochemical, cement, and heavy conveyor applications.
