This gearmotor measures 2.14" in diameter by 7.7" in length, and has a keyed output shaft of 12 mm in diameter by 25 mm in length. Mounting is done with 4 face-mount M5 threaded holes, equally spaced on a 40-mm diameter B.C.

The output of this reversible gearmotor is rated for 125 IN LBS continuous torque, at 37 RPM, and 178 IN LBS peak. It requires 7.2 amp at 12 volts DC to generate its full load torque.
