Description

The NEMA17 FLE42-L1SW Planetary Gearbox (5 : 1) is a compact, high-precision gear reducer engineered for NEMA17 stepper motors.
It enhances torque output and provides smooth, accurate, and efficient motion control, ideal for 3D printers, CNC machines, robotics, and automation equipment.

Built from hardened steel gears with precision bearings and IP54 protection, this gearbox offers long-term reliability, low noise (≤55 dB), and low backlash (≤45 arcmin).
Its 42 × 42 mm housing with an 8 mm key shaft output ensures perfect fit and performance with any standard NEMA17 motor.

Key Features

  • Designed for NEMA17 Stepper Motors — direct mounting compatibility.

  • 5 : 1 reduction ratio — balances torque gain and speed precision.

  • Rated Torque 10 N·m, Sudden Stop Torque 20 N·m.
