Nema 23 Stepper Motor 113mm Gear Ratio 20:1 Worm Gearbox NMRVS30 Worm Gear Speed Reducer

This Nema 23 size 113mm stepper motor is equipped with a 20:1 worm gearbox that has excellent mechanical strength and particularly lightweight. The worm gear speed reducer comes with synthetic oil and allow for universal mounting positions, with no need to modify lubricant quantity.
Its output shaft is offset by 90° from the drive shaft and characterized by high efficiency and self-locking.
Strong capacity for loading and overload ensures stable transmission, with less vibration and noise, making it a good choice for applications such as CNC Router, Engraving, Milling, and Lathe.
