Rossi
Industrial Gearmotors
Industrial gearmotors from Rossi combine high‑performance gear reducers with premium‑efficiency electric motors in a single, compact power‑transmission package purpose‑built for heavy‑industry environments. Unlike standard gearmotors, these industrial‑grade units are engineered to withstand extreme loads, shock forces, continuous duty cycles, and harsh ambient conditions — making them the preferred choice for mining conveyors, cement kilns, steel mill rollers, marine winches, and large‑scale material handling systems. Rossi's industrial gearmotor portfolio encompasses helical and bevel helical units (G Series), planetary gearmotors (EP Series), coaxial gearmotors (E Series), and worm‑wheel gearmotors (A and AS Series). Nominal torques span from 30 Nm to 3,000,000 Nm, with output speeds tailored through transmission ratios ranging from 3.5:1 to over 10,000:1. Every industrial gearmotor is engineered for maximum uptime: case‑hardened and ground gear profiles ensure smooth, low‑noise operation, while robust cast‑iron housings provide structural rigidity even under peak loads.

Why Choose Rossi Industrial Gearmotors for Heavy‑Duty Applications
Heavy‑industry environments — mining pits, cement plants, steel mills, offshore platforms — place extraordinary demands on power transmission equipment. Rossi industrial gearmotors feature oversized bearings, reinforced output shafts, high‑capacity oil sumps, and optional forced‑ventilation or cooling‑coil systems that maintain safe operating temperatures even under continuous full‑load conditions. The modular architecture of the G Series and EP Series allows engineers to select the exact combination of gear stages, ratios, mounting positions, and motor specifications needed. For ATEX‑classified zones, Rossi offers certified gearmotor variants that meet the strictest explosion‑protection standards.
Key Applications and Industries for Industrial Geared Motors
Rossi industrial gearmotors are deployed in the world's most demanding sectors. In mining and quarrying, they power belt conveyors, bucket‑wheel excavators, stacker‑reclaimers, and apron feeders. Cement and aggregates plants depend on Rossi planetary gearmotors for vertical roller mills, rotary kilns, and ball mills. The metal industry uses Rossi helical bevel gearmotors for roller tables, shears, straighteners, and coilers. In marine and offshore, DNV‑approved planetary gearmotors drive mooring winches, windlasses, and crane slewing mechanisms. Water treatment facilities utilize large‑ratio worm and planetary gearmotors for Archimedean screw pumps and clarifier scrapers.
