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-driving the gearmotor so a posture can be held even when power is not applied. The precision ground 3/8” stainless steel output shaft is backed 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 Standard Spur Gear motors will work with this gearbox (engine offered 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 had a need to achieve ten minutes per rotation (at max speed)
