worm wheel gearbox
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-driving the gearmotor therefore a posture can be held even when power is not applied. The precision ground 3/8” stainless steel output shaft is backed by dual 3/8” ABEC 5 ball bearings to support lots from any orientation. The ¼” ABS plastic and light weight aluminum structure provides a rigid framework without adding unnecessary excess weight and is conveniently mounted 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 / (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)
