172:1 Metal Gearmotor 25Dx56L mm HP

This cylindrical, 2.2" x 0.98" x 0.98" gearmotor uses a brushed DC motor with extra-strong magnets and a 172:1 metal gearbox to deliver a lot of power in a relatively small package. These units have a 0.315"-long, 4 mm-diameter D-shaped output shaft. We also carry a lower-power version of this gearmotor. Key specs at 6 V: 57 RPM and 450 mA free-run, 260 oz-in (18.7 kg-cm) and 6 A stall. (Note: stall torque and current specifications are theoretical values; stalling the motor is likely to damage the gearbox.)
