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-traveling the gearmotor so a posture can be kept even when power is not applied. The precision floor 3/8” stainless steel result shaft is backed by dual 3/8” ABEC 5 ball bearings to aid a load from any orientation. The ¼” ABS plastic and aluminum structure offers a rigid framework without adding unnecessary weight and is certainly easily 
mounted to any flat surface by utilizing the base mounting tabs. Our Standard Spur Gear motors will work with this gearbox (motor marketed separately). The Vertical Shaft Worm-Drive Gearbox is ideal for turn-tables, time-lapse systems and low-rate 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 needed to achieve 10 minutes per rotation (at max speed)
