Electric Cylinders N2 / EC Series







            Electric cylinders are thrust-producing devices that are best suited for applications requiring high axial force with the moment
            and side loads already properly supported.
            Kollmorgen has combined the broad product offering of the N2 and EC Series electric cylinders with the industry-leading AKM
            servo motors and AKD servo drives. The N2 and EC Series of electric cylinders offer a wide range of available thrusts in standard
