164.63:1 LP Metal DC Geared-Down Motor 25Dx47.8L mm 2.5W/12V, with Fix Bracket.

This gearmotor consists of a low-power, 12 V brushed DC motor combined with a 164.63:1 metal spur gearbox. The gearmotor is cylindrical, with a diameter just under 25 mm, and the D-shaped output shaft is 4 mm in diameter and extends 12.5 mm from the face plate of the gearbox. At 12V, the speed is 5700 rpm before the motor decelerates.

Warning: Do not screw too far into the mounting holes as the screws can hit the gears. CQRobot recommend screwing no further than 6 mm (0.24″) into the screw hole.
