High power density solution Compact Electro-Mechanical Cylinder to meet the automation market challenges The latest generation of Compact Electro-Mechanical Cylinder (CEMC) is part of the Ewellix heavy duty actuator series. The planetary inverted roller screw technology allows the integration of hollow shaft motors directly onto the roller screw nut, resulting in a very compact yet powerful solution. As well as its external dimension, this design minimizes inertia for excellent control, responsive performance, reduced cycle time and higher productivity. 1. Lubrication grease fitting 2. Push tube 3. High quality angular contact ball bearings 4. High quality planetary inverted roller screw for highest axial load rating, low axial play and high efficiency 5. Integrated hollow shaft servo motor 6. Motor connectors 7. Fail safe brake option 8. Position feedback options for compatibility with main brands of robots/controllers 9. Scraper seal to keep contamination out CEMC benefits Construction with individual modules and various options, more than 300 possible configurations, to match customer application requirements. High reliability of inverted roller screw technology for long service life with millions cycles. Aluminum housings and reduced number of components, resulting in light weight for easy integration in automation equipment. CEMC main output data Compact design within 100 mm square frame, fitting in small spaces, while offering high power density and force up to 25 kN. The CEMC series combines multiple tried and tested technologies to provide best-in-class performances for applications such as resistance spot welding, joining, dispensing, pressing, assembly operations, where high force, robustness and productivity are essential.
