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-driving the gearmotor so a position can be held even when power is not applied.  The precision ground 3/8” stainless steel output 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 easily mounted to any flat surface by utilizing the base mounting tabs.  Our Standard Spur Gear motors will work with this gearbox (motor sold separately).  The Vertical Shaft Worm-Drive Gearbox is perfect for turn-tables, time-lapse systems and low-speed applications that require 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 10 minutes per rotation (at max speed)
