Our Advantages:
With 10 years experienced engineer, we can custom made the
performance you need. We can adjust the voltage, speed of the
motor, and design the suitable reduction ratio of the gearbox. We
can develop new type gearbox according to your requirements if your
quantity can meet our requirements.
We can produce the gears by our own hob machine, which we can
control the quality of gearbox better. We’re one company who can
produce both the motor and the gearbox, in this case, we can
provide high quality control for the whole gear motor.
