ESR Pollmeier GmbH - Servo Drive Technology

Ball Screw Axes

A ball screw axis consists of a linear module with ball screw by which a carriage can be moved back and forth, and a rotatory servo motor providing for the motion.

Advantages of the ESR ball screw linear modules:

The linear modules can be combined with all ESR AC servo motors.
