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 merely minimizes backlash but also eliminates back-driving the gearmotor so a position can be kept 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 support a load from any orientation. The ¼” ABS plastic and light weight aluminum structure offers a rigid framework without adding unnecessary weight and is certainly easily installed to 
any flat work surface by utilizing the base mounting tabs. Our Regular Spur Gear motors will continue to work with this gearbox (electric motor sold separately). The Vertical Shaft Worm-Drive Gearbox is perfect for turn-tables, time-lapse systems and low-acceleration applications that want high precision and torque.
Motor RPM required = 1 / (moments per rotation desired / 30)
Example: 1 / (ten minutes per rotation / 30) = 3 RPM motor needed to achieve ten minutes per rotation (at max speed)
