GMGM Series Gear Reducer (GM10–GM90)
Modular High-Power Reducers GUOMAO GM

GM is the GUOMAO modular heavy-duty industrial gear unit range (catalogue NO.005), 9 sizes GM10–GM90. Two gear types: parallel-shaft helical (2, 3 and 4 stages, ratios 6.3–400) and right-angle bevel-helical (3, 4 and 5 stages, ratios 14–1,800). Input power 2.8–2,975 kW, rated output torque 5.4–183 kN·m, maximum torque twice the rated value. The low-speed shaft is horizontal or vertical, solid (S) or hollow (H); mounting on feet (F), on a torque arm (T) or by flange. Efficiency 0.97 / 0.955 / 0.94 / 0.93 for two, three, four and five stages.
