5:1 Planetary Gearbox For Nema 34 Stepper Motor With 86mm Frame And 20mm Output Shaft Dual Input Shafts 14mm And 12.7mm 7 Arc-Min Backlash Beefy Torque Gear Reducer Box 3500RPM 90x90mm Housing For Precise Motion

5:1 Planetary Gearbox for Nema 34 Motor, 90x90mm 1pc
✔️ 5:1 ratio, 122 Nm torque, input shafts 14mm/12.7mm, 20mm output

This planetary gearbox is designed for NEMA 34 stepper motors and fits a compact 90x90 mm (3.54x3.54 in) housing. It accepts dual input shafts of 14 mm and 12.7 mm and provides a 20 mm output shaft, enabling flexible motor pairing. With a 5:1 reduction, you get high torque at low speeds for precise motion control in automation, CNC, and robotics. Built from alloy steel, it delivers strong durability, low noise (under 60 dB), and a long service life around 20,000 hours. The kit includes 1 gearbox, 4 mounting screws, and a 14 mm to 12.7 mm shaft adapter to fit different motor shaft standards.
