ESR Pollmeier GmbH - Servo Drive Technology

Ball Screw Actuators

With their compact design, ball screw actuators are an excellent replacement for hydraulic cylinders. In combination with a rotatory servo motor, the integrated ball screw moves a piston rod.

Advantages of the ESR ball screw actuators:

The ball screw actuators can be combined with all ESR AC servo motors.
