Product Overview Because of the actuator choices that electromechanical drive solutions offer, they are becoming more and more widespread as an alternative to fluid driven technology. The Electromechanical Cylinder EMC from Rexroth is a powerful alternative to pneumatic cylinders while providing significant benefits in terms of energy efficiency, a prime goal in engi- neering today. It also offers clear conceptual advantages, allowing travel to any intermediate target position as well as creating greater flexibility through higher thrust and variable speeds. Combinations of the various...
