MGL Series Planetary Gearbox Gear Ratio 50:1 Backlash 45arc-min for 5mm Shaft Standard Nema 17 Stepper Motor

The MGL series high-precision planetary gearbox features a gear ratio of 50:1 and a maximum backlash of 45arc-min. Different with MG series gearboxes, the MGL series is designed to accommodate standard Nema 17 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 5mm diameter standard shafts of Nema 17 stepper motors, brushless DC motors, and brushed DC motors.
