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 only minimizes backlash but also eliminates back-traveling the gearmotor so a position can be held even when power isn’t applied. The precision surface 3/8” stainless steel result shaft is supported by dual 3/8” ABEC 5 ball bearings to support a load from any orientation. The ¼” ABS plastic and aluminum structure provides a rigid framework without adding unnecessary weight and is certainly easily installed to any flat surface by utilizing the base mounting tabs. Our Regular Spur Gear motors will continue to work with this gearbox (motor sold separately). The Vertical Shaft Worm-Drive Gearbox is perfect for turn-tables, time-lapse systems and low-quickness applications that require high precision and torque.
Motor RPM required = 1 / (moments per rotation desired / 30)
Example: 1 / (ten minutes per rotation / 30) = 3 RPM motor had a need to achieve 
10 minutes per rotation (at max speed)
