Electric Cylinder


Parker’s Electromechanical Automation Division  announces the release of its ETH Series electric cylinder. The Parker ETH series is a next-generation rod-style actuator based upon the well-known, widely-used ET Series. This ground-up redesign offers unrivaled power density due to the use of oversized ballscrews and thrust bearings in traditional package sizes. The result is a product that is capable of increased force output form a given frame size, or increased product life at the same force output.

Available in three profile sizes, the ETH can be ordered with either in-line or parallel motor mounting configurations. A choice of three leads per profile size allows the user the flexibility to match the actuator’s performance to the application’s requirements.

The ETH series combines unparalleled design with a variety of options that make it easy to integrate into both new and existing applications. Designed around hard metric ISO standards, the ETH Series can mount into existing fluid power cylinder applications, adding infinite programmability to the durability and long life expected from hydraulic and pneumatic cylinders.

The ETH electric cylinder closes the gap between electromechanical and hydraulic cylinder performance, making it suitable to use in higher force applications where increased reliability is required in the production process. “Taking the costs of the hydraulic system components into consideration, you will find that in most cases, an electromechanical system such as the ETH electric cylinder offers the more economical solution,” says Michael Szesterniak, product manager.
