Integral Squeeze Film Damper

Leading Vibration Solution

     ISFD® technology provides highly engineered damping and stiffness to allow exact placement of critical speeds and increase the dynamic stability of rotor/bearing systems.

     In the patented ISFD design, stiffness and damping are independent of each other and can be precisely controlled. This produces higher and more accurate damping capability than a conventional squeeze film damper and makes ISFD technology a leading solution for controlling vibrations in mainstream and emerging applications.

     Stiffness and damping are each optimized for the application through rigorous rotordynamic analysis.
