This worm gearbox is designed for Nema 34 Stepper Motor or other 86mmx86mm 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.
