Parker Hannifin is extending its range of high-force electro thrust cylinders with the introduction of the new ETH100. The ETH100 combines the advantages of hydraulics with those of electronics, profiting from its rugged design and the resulting long service life. Typical applications for the ETH100 include material-forming and press applications, food processing and packaging machinery, industrial automation and other applications where users are looking for an energy saving electro cylinder for precise positioning and force control.
As with the frame sizes ETH032, ETH050 and ETH080, the development of the ETH100 focused on realising an extraordinary force density (force per frame size). The precision-ground ball screw is the centre piece of the construction. The ETH cylinder offers low friction, an efficiency of up to 90 per cent, smooth operation over the entire speed range and a long service life. Thanks to the high availability of the ball screw, short lead time and attractive prices are guaranteed. Like its smaller ‘siblings’, the ETH100 features an integrated anti-rotation device as a standard, which simplifies the integration of the cylinder into customer systems. The standard central lubrication port integrated into the cylinder body helps reduce maintenance overhead and downtimes to a minimum.
The ETH100 is available with screw leads of 10mm and 20mm. It is able to achieve thrust forces of up to 56000N, travel speeds of up to 666mm/s and accelerations of up to 10m/s2. ETH100 comes in defined standard travel lengths between 100mm and 2000mm, but is configurable in steps of 1mm also. With a repeatability of up to 0.05mm, the ETH100 is suitable for all tasks requiring precise motion, positioning, setting and actuating.
Like all cylinders of the ETH series, the ETH100 is available with parallel or inline motor configuration. Thanks to a variety of mounting options, which can be chosen according to customer requirements, customers may combine the cylinder with many different motors and gearboxes. The number of rod end configurations and mounting options offer the flexibility to integrate the electro cylinder into customer’s applications. Available sensors and cables can be directly immersed into a groove in the ETH profile, which may then be protected by a cover. This ensures a smooth surface for easy cleaning and safe handling.
The ETH is offered as standard in IP54 format with galvanised screws, but is also available with stainless steel screws or in full IP65 format with additional coating protecting the cylinder against aggressive chemicals, thus meeting the needs of more demanding environmental conditions. Simplifying product selection and mounting, Parker can also provide a complete drive train, including matching servo drive controllers, motors and gearboxes. All these components can be selected and programmed easily with the easy-to-use Compax3 software-tools.
