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