Electric Cylinder - ISO15552

EC*3 Series Electric Cylinder

The EC*3 series electric cylinder from Duplomatic is a high-performance linear actuator designed to deliver precise, controlled motion across a wide range of industrial applications. Built in accordance with ISO 15552 standards, this electric cylinder provides full compatibility with standard pneumatic mounting interfaces, allowing machine builders to transition from pneumatic or hydraulic systems to electric actuation without major redesign.

With a strong emphasis on mechanical integrity, flexibility and long service life, the EC*3 electric cylinder is engineered to meet the demands of modern automation environments where accuracy, repeatability and energy efficiency are critical.

Electric Cylinder Design and Construction

At the heart of the EC*3 actuator is a precision ball screw drive system, manufactured from hardened, high-strength steel to ensure durability and consistent performance. This drive mechanism enables efficient conversion of rotary motion into smooth, controlled linear movement, providing excellent positioning accuracy and repeatability over extended operating cycles.

The internal construction has been carefully optimised to minimise vibration and maximise rigidity. A zero-backlash piston guidance system ensures stable motion within the barrel, while high-capacity bearings support the screw to maintain alignment and handle loads in both directions. The rod itself is designed with increased diameter and wall thickness, improving resistance to buckling and radial forces, particularly in longer stroke applications.

This robust mechanical design allows the electric cylinder to perform reliably even in demanding industrial environments, where consistent accuracy and long operational life are essential.

Electromechanical Actuator Performance and Range

The EC*3 electric cylinder range offers a high degree of flexibility, with bore sizes from 32 mm to 125 mm and stroke lengths available up to 3 metres. This wide range allows engineers to select an electric cylinder that precisely matches their application requirements, from compact automation tasks to heavy-duty linear motion systems.

Depending on the selected size and configuration, the electric cylinder is capable of handling substantial dynamic loads and delivering high thrust forces. This makes it a practical alternative to hydraulic systems in many applications, particularly where controlled motion, reduced maintenance and cleaner operation are required.

In addition, the availability of both standard and oversized ball screw configurations provides further optimisation, enabling higher load capacity and extended service life in more demanding use cases.

Installation and Flexibility

One of the key advantages of the EC*3 electric cylinder is its adaptability to different machine layouts. The unit can be supplied with either inline or parallel motor mounting configurations, allowing designers to optimise space utilisation within their equipment. In parallel arrangements, a high-strength timing belt ensures efficient and reliable torque transmission between the motor and the screw.

The ISO 15552 design also means that the electric cylinder can utilise a wide range of standard pneumatic mounting accessories, simplifying installation and reducing the need for custom brackets or interfaces. Additional options, such as an integrated anti-rotation device, further enhance stability and ensure consistent linear motion in applications where precise guidance is required.

This level of flexibility makes the EC*3 electric cylinder particularly attractive for OEM machine builders looking for a modular and easily integrated actuation solution.

Electric Ball Screw Actuator for Precision Automation

The EC*3 series electric cylinders are ideally suited to applications where accurate positioning and controlled motion profiles are essential. The use of ball screw technology allows for smooth acceleration and deceleration, enabling precise control of speed and position even under load.

Integrated magnetic sensing capability allows the cylinder to accommodate position sensors within external grooves, providing reliable end-of-stroke detection and supporting advanced automation processes. This makes the electric cylinder highly effective in systems requiring synchronisation, repeatability and feedback-driven control.

Typical applications include automated handling systems, assembly machinery and equipment where consistent, programmable linear motion is required without the complexity of hydraulic systems.

Electric Cylinder Reliability and Environmental Protection

Designed for industrial use, the EC*3 electric linear actuator offers protection ratings up to IP65, ensuring reliable operation in environments where dust and moisture are present. It is capable of operating across a wide temperature range and supports continuous duty cycles, making it suitable for demanding production environments.

The elimination of hydraulic fluid not only reduces maintenance requirements but also supports cleaner and more environmentally friendly operation. This makes the electric cylinder an increasingly popular choice in industries where contamination, noise reduction and energy efficiency are key considerations.

Integration and Application Benefits

The EC*3 electric cylinder provides a compelling combination of performance, flexibility and ease of integration. Its ISO-compliant design, wide configuration options and robust construction allow it to be used as a direct replacement for pneumatic or hydraulic cylinders, while offering the additional benefits of precise control and programmable motion.

For machine builders and system integrators, this means reduced system complexity, improved efficiency and greater control over motion profiles. As industrial systems continue to evolve toward smarter and more energy-efficient solutions, the EC*3 electric cylinder stands out as a reliable and future-ready actuation technology.
