Modern Robotics/MATRIX 12VDC Motor with 8mm REX™ Pinion Shaft

SKU:
$24.99

This is the motor that drives the popular Yellow Jacket Planetary Gear Motors, but with a bit of a twist. Where you would typically find a press-fit pinion gear, we’ve installed an 8mm REX™ pinion shaft. What’s a pinion shaft? - well, we didn’t want to cause confusion between the factory motor shaft, which measures 0.125”, and the shaft that fits onto it, hence the unique name. The 8mm REX™ output shaft protrudes 36mm from the mounting face of the motor so you have plenty of real estate to attach a gear, pulley or hub to, while still leaving room for an 8mm REX™ bearing to add that bit of necessary support. The motor has a tested speed of 5800RPM, so put on your safety glasses and let it rip!
