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 again-driving the gearmotor therefore a posture can be held even when power is not applied. The precision floor 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 fat and is easily mounted to any flat surface by utilizing the base mounting tabs. Our Standard Spur Gear motors will work with this gearbox (motor offered separately). The Vertical Shaft Worm-Drive Gearbox is ideal for turn-tables, time-lapse systems and low-price applications that want high precision and torque.
Motor RPM required 
= 1 / (mins per rotation desired / 30)
Example: 1 / (10 minutes per rotation / 30) = 3 RPM motor had a need to achieve 10 minutes per rotation (at max speed)
