Rotary Actuators
Industrial rotary actuators from global suppliers. Technical specifications, documentation, and RFQ capabilities.
Rotary actuators integrate a precision harmonic drive gear with a brushless servo motor and encoder into a single compact unit. The hollow shaft design allows cables, pneumatic lines, or laser beams to pass directly through the axis of rotation.
LVH Systems sources hollow shaft and solid shaft rotary actuators from Harmonic Drive LLC across peak torques from 2.2 Nm to 2500 Nm. Available with CANopen, EtherCAT, and analogue interfaces. Custom shaft configurations and gear ratios available.
