The ServoCity Super-Duty Worm Drive Gearbox (28:1 Ratio) is engineered with a robust all-aluminum framework designed to handle substantial loads with ease. It features a 28:1 gear ratio that significantly reduces motor speed, thereby delivering a high level of torque. The worm drive mechanism ensures that the output shaft remains securely locked in place until power is applied to the motor. This gearbox is equipped with a versatile hub on the top, allowing for various mounting configurations, including plates, channels, or arms. It is compatible with goBILDA® 5203 Series Yellow Jacket Gear Motors, providing flexibility in motor selection. The kit includes all essential components required for operation, excluding the motor itself.
