GRGR Series Helical Geared Motor (GR19–GR179)
Helical Geared Motors GUOMAO GR
GR in-line helical geared motors are the backbone of the GUOMAO modular range: input and output shafts with small eccentricity, two or three stages of helical gears. 14 sizes GR19–GR179, maximum output torque 85–36,600 N·m, motor power 0.12–160 kW, ratios 1.3–26,995 including the GR..R combined units. High-strength cast-iron housing; gears and pinion shafts are gas-carburised, quenched and precision-ground; gear stage efficiency above 95 %. Versions: foot-mounted (GR), B5 flange (GRF), flange with extended bearing housing for agitators (GRM), and a separate-drive input version (GR..AD).
