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 sizing steps help you to find the suitable electro cylinder. Select an electro cylinder using estimated application data. Calculate the actually required application data following the dimensioning steps described below. If your application’s requirements exceed a maximum value, please choose a larger electro cylinder and recheck the maximum values. Perhaps, a smaller electro cylinder can also meet the requirements. Automated dimensioning with the help of the "EL Sizing Tool" A dimensioning...

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...

ETH - Electro Cylinder Lifetime Service Life Nominal service life1, 2 The nominal service life of the electro cylinder can be determined with the aid of the diagrams page 14. The forces calculated for each individual segment of the application cycle must be summarized into an equivalent axial force Fm "Calculating Required Axial Force" (page 11). If axial forces with different signs apply, two equivalent axial forces must be calculated: • Fm1 for all positive forces. The negative forces will convert to zero. • Fm2 for all negative forces. The positive forces will convert to zero. F With the...
