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-generating the gearmotor so a posture can be kept even when power is not applied. The precision floor 3/8” stainless steel output shaft is supported by dual 3/8” ABEC 5 ball bearings to aid lots from any orientation. The ¼” ABS plastic and aluminium structure provides a rigid framework without adding unnecessary weight and is usually easily mounted to any flat surface by utilizing the base mounting tabs. Our Standard Spur Gear motors will continue to work with this gearbox (motor offered separately). The Vertical Shaft Worm-Drive Gearbox is ideal for turn-tables, time-lapse systems and low-quickness applications that require 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 (in max speed)
