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 merely minimizes backlash but also eliminates back-generating the gearmotor so a posture can be held even when power isn’t applied. The precision ground 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 aluminum structure offers 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 continue to work with this gearbox (motor offered 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 / (mins per rotation desired / 30)
Example: 1 / (10 minutes per rotation / 30) = 3 RPM motor needed to achieve 10 minutes per rotation (at max speed)
