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 held even when power is not applied. The precision ground 3/8” stainless steel result shaft is supported by dual 3/8” ABEC 5 ball bearings to support lots from any orientation. The ¼” ABS plastic and aluminum structure provides a rigid framework without adding unnecessary weight and is certainly easily mounted to any flat work surface by utilizing the bottom mounting tabs. Our Regular Spur Gear motors will continue to work with this gearbox (engine sold separately). The Vertical Shaft Worm-Drive Gearbox is perfect for turn-tables, time-lapse systems and low-quickness applications that require high precision and torque.
Motor RPM required = 1 / (mins per rotation desired / 30)
Example: 1 / (10 minutes per rotation / 30) = 3 RPM motor needed to achieve ten minutes per rotation (at max speed)
