Product description
Hygienic, flexible, energy-efficient. Its high variability makes the Electromechanical Cylinder so interesting for many industries and applications. By using the available configuration options, a cheaper, simpler base cylinder can be adjusted to virtually any customer requirement: chemical resistant, with perfect sealing and a high IP type of protection. All these properties ensure a long life – even under harsh industrial conditions. The powerful Electromechanical Cylinder always performs very efficiently. The resulting energy saving potential makes it an economical alternative to pneumatic systems.
The mechanical system in the Electromechanical Cylinder EMC is based on proven Rexroth Ball Screw Assemblies in a wide range of diameter and lead combinations. The Rexroth Ball Screw Assembly converts torque into linear motion with high mechanical efficiency. During this process, the piston rod fastened to the Screw Drive nut is extended and retracted. Both the Screw Drive nut and the piston rod are guided in the housing and cannot twist.
