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.
