KMD-50 & KMD-60 Electromechanical Actuators
June 2, 2017 – Rochester, New York, USA – ORMEC is pleased to announce the arrival of the KMD-50 and KMD-60 Electromechanical Actuators.
The KMD-50 and KMD-60 are the first of a line of electromechanical actuators providing a powerful and efficient alternative to hydraulic or roller screw actuators applications such as pressing, metal and Thermo-Forming and other high load applications.
Designed and assembled in Rochester, NY the KMD Actuators are based on world class ball screw technology that is quieter and more efficient than other solutions. Optimized to work with ORMEC Servo Motors, option for 3rd party motors are also available.
Specifications for the KMD-50 and KMD-60 are shown in Table 1.
