This Nema 23 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. Model
