Festo ERMO Rotary Actuators

Festo ERMO Rotary Actuators are compact electric rotary units with a robust output flange and an integrated motor with a gear stage. The series is ideal as a precise front unit for handling solutions and as a compact rotary table in space-optimized systems. Additional features include motor control with an encoder for high angular accuracy and robust output bearings that absorb high forces and torques. Festo ERMO Rotary Actuators include a backlash-free pre-stressed rotating plate with good axial eccentricity and concentricity properties. The ERMO series offers quick and accurate installation for a wide range of applications.
