Description

Enhance your NEMA 17 stepper motor with this new, more compact version of the 1:4 planetary gearbox. Designed for high torque output, precise control, and a reduced footprint, this gearbox is perfect for robotics, CNC systems, and motion control applications. Now featuring an insert coupling for easier and more secure shaft connection, it's an ideal solution for demanding projects by makers and engineers alike.

Key Features:

  • Gear Ratio: 1:4 – Multiplies torque by 4 and reduces output speed for greater control and holding force
  • Compact Planetary Design – Centralized power transmission in a space-saving form
  • Motor Compatibility: Standard NEMA 17 stepper motors
  • High Efficiency: Smooth and durable operation with a balanced gear system
  • Low Backlash: Perfect for precision applications such as 3D printers, robotic arms, and linear actuators
  • Robust Construction: Made with high-precision, wear-resistant components for long-lasting performance
  • New Insert Coupling: Simplified assembly with a secure fit to the motor shaft – no machining required

Required Hardware (not included):

  • 4 × M4x20 screws – for gearbox housing assembly
  • 3 × Countersunk M4x10 screws with nuts – for fastening critical components
  • 7 × Threaded inserts – for a strong, reliable assembly
  • 1 × Ball bearing – 22 mm outer diameter, 8 mm inner diameter (for shaft support)
