Smart actuator|hollow shaft rotary actuators|zero

The intelligent flexible actuator SCA is mainly divided into four series, which are the QDD Pro series with harmonic reducer, the QDD series with planetary reducer, the composite material version QDD Lite series and the DD series without reducer.

QDD Pro-NU80-100-110 Parameter

Note:The actual reduction ratio is the harmonic nomical gear ratio plus 1 because the flexspline is fixed.
