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 position can be kept 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 aid lots from any orientation. The ¼” ABS plastic and aluminium structure offers a rigid framework without adding unnecessary weight and is definitely easily mounted to any flat work surface by utilizing the bottom mounting tabs. Our Regular Spur Gear motors will continue to work with this gearbox (electric motor sold separately). The Vertical Shaft Worm-Drive Gearbox is ideal for turn-tables, time-lapse systems and low-quickness applications that want high precision and torque.
Motor RPM required = 1 / (minutes per rotation desired / 30)
Example: 1 / (10 minutes per rotation / 30) = 3 RPM motor needed to achieve ten minutes per rotation (in max speed)
