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-generating the gearmotor so a position can be held even when power isn’t applied. The precision ground 3/8” stainless steel output shaft is supported by dual 3/8” ABEC 5 ball bearings to support lots from any orientation. The ¼” ABS plastic and aluminium structure provides a rigid framework without adding unnecessary 
weight and is definitely easily installed 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 perfect for turn-tables, time-lapse systems and low-speed applications that want 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)
