[GGM] — K7G□C Gear Head for 15W Motor (□70mm, Ball Bearing + Metal Bearing, 1/3–1/200, incl. Decimal (K7G10BX))

Family ID: GGM-K7G-C

GGM gear head converts motor speed/torque by gear ratio. Helical-gear precision machining lowers noise approx. 10 dB vs conventional. Ball Bearing + Metal Bearing (C) type, ratios 1/3–1/200 (24 steps); dedicated to □70mm 15W pinion-shaft motor (K7□G), matching face/teeth only. Includes decimal gear head K7G10BX (1/10 intermediate reducer) for ratios beyond 1/200 (speed ÷10; permissible torque 5N·m/50kgf·cm).
