This is the 130-size DC motor used in the larger Pololu plastic gearmotors (228:1 offset, 120:1 offset, 200:1 90-degree, and 120:1 90-degree).
It has a recommended operating voltage of 3 – 12 V;
at 6 V, the no-load speed is about 11,500 RPM,
the no-load current is approximately 70 mA,
and the stall current is around 800 mA.
For an estimate of the torque, note that the Pololu 228:1 plastic gearmotor produces roughly 100 oz-in of torque at 6 V using this motor,
and the Pololu 120:1 plastic gearmotors produce roughly 75 oz-in of torque at 6 V. The output shaft has a diameter of 2 mm.
