20:1 Worm Gearbox NMRV30 Worm Gear Speed Reducer 9mm Input Shaft Diameter
This worm gearbox is designed for Nema 23 Stepper Motor or other 57mmx57mm size motor, the output shaft is offset by 90° from the drive shaft. The advantage for this gearbox is efficiency and self-locking. Besides big cases, no gap structure of box means a maintenance- free that is hermetically sealed. It prevents the lubricant from easily losing and going bad, and exchanging.
