ETH - Electro Thrust Cylinder Overview Product Design Ballscrew A high-quality precision class 7 ballscrew in accordance with ISO 3408 is used. The ball bearings between screw and nut ensure a low frictional resistance. This ensures an especially smooth operation over the entire speed range, high service life and excellent efficiency. Screw support bearing (front end) The front screw support bearing is supported by a polymer sliding bearing. This eliminates vibration and run-out. The result is quieter, smoother motion with better precision, longer screw life, and increased dynamic...

ETH - Electro Cylinder Step by Step Selection Process Step by Step Selection Process The following steps help you to specify the most suitable electro cylinder for your application. If your application’s requirements exceed a maximum value, please choose a larger electro cylinder and recheck the maximum values. In some cases a smaller electro cylinder can also meet the requirements. Application data ATEX or non-ATEX environment If used in an ATEX environment, check if the ETH corresponds to the ATEX requirements of your application "Electro Thrust Cylinder for ATEX Environment" (page 12)...

ETH Electro Cylinder Calculating Required Axial Force Calculating Required Axial Force Formulas 1 & 2 below give the mathematical equation for calculating the thrust required to extend or retract the piston rod. With the aid of the axial forces, it is possible to check if the electro cylinder is able to provide the required forces and if the maximum buckling load is respected. The axial forces are also used as the calculation basis for the service life. Formula symbols (Formula 1-2) = Axial forces during extension in N Fx,a,j FG,Kse FG,Ks = Mass of the cylinder rod at zero stroke in kg =...

ETH - Electro Cylinder Selection of the Size and Screw Lead Selection of the Size and Screw Lead Required maximum axial force Determine the maximum axial force (page 11) that the electro cylinder must provide. Preselection of the electro cylinder Using the calculated force required, compare the actual electro cylinder specifications (page 8) to determine which profile size will produce enough force. Once you have determined a profile size, determine that the unit will physically fit in the space allowed by the application (including parallel or inline motor mounts). Required maximum...
