    • PLANETARY GEARBOX：speed reducer for servo motor and stepper motors, from 50W to 7500w.
    Planetary gearboxes are widely used as speed reducer of servo motors and stepper motors. Ratio from 3 to 512, our planetary gear boxes are useful in almost any case. The classic SP series are of good quality and good price. The backlash of the high precision SPB helical series can be less than 3(stage 1)and 7(stage 2)
