  • High precision gears and servo motor placed centrically in the load line, moving up and down with the moving crosshead
  • In comparison to standard electromechanical creep testing machines, the Kappa SS - CF creep testing machine stands out because of its excellent linearity force-deflection curve with backlash-free zero crossing 
  • Virtually play-free drive is patent pending: special load train bearing ensures optimum alignment properties in accordance with ISO 23788 and NADCAP requirements
  • Load frame with single lead screw drive and precision guidance provided via 4 steel columns, giving precise axial loading and maximum durability
  • High-resolution force and travel measurement for optimum control properties, especially at very low test speeds
  • Constant moving crosshead speed via precision central ball screw
  • Optional digital closed loop control for force and strain
  • The large range of machine accessories offers flexible application options, which are complemented by testControl intelligent electronics and testXpert software.
