This Nema 34 size stepper motor is equipped with a 5:1 worm gearbox. The worm gear speed reducer comes with a high-quality, long-term synthetic lubricant, which makes it maintenance free. Its output shaft is offset by 90° from the drive shaft and characterized by high efficiency and self-locking.
Strong capacity of loading and overload ensure stable transmission, make less vibration and noise. It's good choice to be applied to CNC Router, Engraving, Milling, Lathe, etc.
