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-traveling the gearmotor so a position can be kept even when power isn’t applied. The precision floor 3/8” stainless steel result shaft is supported by dual 3/8” ABEC 5 ball bearings to support lots from any orientation. The ¼” ABS plastic and aluminum structure provides a rigid framework without adding unnecessary weight and is definitely easily mounted to any flat work 
surface by utilizing the base mounting tabs. Our Standard Spur Gear motors will continue to work with this gearbox (engine offered separately). The Vertical Shaft Worm-Drive Gearbox is perfect for turn-tables, time-lapse systems and low-swiftness applications that want high precision and torque.
Motor RPM required = 1 / (moments per rotation desired / 30)
Example: 1 / (10 minutes per rotation / 30) = 3 RPM motor needed to achieve ten minutes per rotation (at max speed)
