I have 3 sets of these. I got them for making something move in my display. The motor is 24vdc and has a gear box built in to it. Has a nice mounting bracket. The drive gear is 7 inch in diameter. It has a ball bearing mount. It has a cam that fits in the groove of the large gear. Also an optical sensor for the ear on the large cam gear. Even without the large gear the motor has good torque even at 12 and 18 volts. For sale $25 or trade for about anything! Okc zip 73139
