  • High torque Long life usage Durable Low noise
  • Gearbox Type: Planetary, Material: Metal, Quantity: 1 piece, Flange: 57mm, Gear Ratio: 20:1, Backlash at No-load: ≤45arcmin
  • In contrast to the MG series, the MGL series is specially designed to support standard Nema 23 motors with standard shafts and therefore offers greater flexibility in the combination of motor and gearbox.
  • This in-line planetary gearbox is equipped with a built-in input shaft coupling that ensures compatibility with standard 8mm diameter shafts used in Nema 23 stepper motors, brushless DC motors and brushed DC motors.
  • Included: 1pc x Planetary Gearbox 4pc x Screws


The MGL series high-precision planetary gearbox features a gear ratio of 20:1 and a maximum backlash of 45arc-min. Different with MG series gearboxes, the MGL series is designed to accommodate standard Nema 23 motors with standard shafts. This allows for more flexibility in the motor matching gearbox.
This inline planetary gearbox comes with a built-in input shaft coupling, making it compatible with standard 8mm diameter standard shafts of Nema 23 stepper motors, brushless DC motors, and brushed DC motors.
