## Description

This gearbox is built like a brick! Its all-aluminum framework houses massive 12mm bearings to take on 200lbs of load with ease. Its 28:1 ratio reduces the speed of your motor by 28X to provide a tremendous amount of torque. And thanks to its worm setup, its output shaft is locked into place until you send power to your motor. The hub on the top gives you multiple options for mounting a plate, channel or arm.

This kit includes all necessary components, minus a motor, to get you up and running with worm drive action. This kit is compatible with [goBILDA® 5203 Series Yellow Jacket Gear Motors.](https://core-electronics.com.au/gobilda/motion/motors/yellow-jacket-planetary-gear-motors.html)
