This gearbox utilizes a 30:1 ratio worm-drive reduction for applications that require extremely slow and smooth rotational motion. The worm-drive design not only minimizes backlash but also eliminates back-generating the gearmotor so a posture can be kept even when power isn’t applied. The precision ground 3/8” stainless steel output shaft is supported by dual 3/8” ABEC 5 ball bearings to aid lots from any orientation. The ¼” ABS plastic 
and light weight aluminum structure offers a rigid framework without adding unnecessary weight and is certainly easily mounted to any flat surface by utilizing the bottom mounting tabs. Our Standard Spur Gear motors will work with this gearbox (engine marketed separately). The Vertical Shaft Worm-Drive Gearbox is ideal for turn-tables, time-lapse systems and low-quickness applications that want high precision and torque.
Motor RPM required = 1 / (a few minutes per rotation desired / 30)
Example: 1 / (ten minutes per rotation / 30) = 3 RPM motor needed to achieve 10 minutes per rotation (in max speed)
