Brief introduction


Gear box is used to transfer rotation and torque from motor to working machine,


the function is to decrease speed by gears and increase torque.

*Main characteristic

low backlash
high output torque-the industry's highest torque density
balanced motor pinion
high efficiency(up to 97%)
ratio 3:1 to 512:1
low noise
operable in any mounting positions
lifetime lubrication
