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-driving the gearmotor so a position can be held even when power isn’t applied. The precision surface 3/8” stainless steel result shaft is backed by dual 3/8” ABEC 5 ball bearings to support a load from any orientation. The ¼” ABS plastic and aluminium structure provides a rigid framework without adding unnecessary weight 
and is usually 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-swiftness applications that require high precision and torque.
Motor RPM required = 1 / (mins per rotation desired / 30)
Example: 1 / (ten minutes per rotation / 30) = 3 RPM motor had a need to achieve 10 minutes per rotation (at max speed)
