The size of this gearbox is 57 x 57mm and the input shaft diameter is 8mm. This high-precision planetary gearbox is belong to MG series gearbox, it with gear ratio 20:1 and a maximum 50arc-min backlash. Diffent with the EG series' steel gears, MG series' gears are made of powder metallurgy. It's an excellent choice for applications that require good accuracy but low cost.
This inline planetary gearbox built-in an input shaft coupling which can match standard 8mm diameter short shaft of Nema 23 stepper motor, brushless dc motor and brushed dc motor.
One of matchable motor is 23HS30-2904S, for other motors, please contact our technical support to custom the motor shaft.
