Product Overview
  • The SM-1 negative-stiffness isolator is the basic building block of the FP-1 Floor Platform and other heavy multiple isolator systems. They require no air or electricity.

    This isolator has the same basic features of our all passive, negative-stiffness, manually-adjustable bench top isolators. It offers our very-low frequency isolation performance for payloads of many thousands of pounds.

    The SM-1 isolator can be used alone or with any number of additional units to achieve higher capacity systems. They can be arranged in many geometrical configurations to suit your application.

    If there is a need, the isolators can be customized to achieve user specific needs. Eg., different horizontal and vertical frequencies, dampening, etc. They can also be made cleanroom and vacuum capatible.

    The SM-1 isolators can also be placed on pedestals to increase the height of the isolation system.

    • Vertical natural frequency of 1/2 Hz or less can be achieved over the entire load range.
    • Horizontal natural frequency is load dependent. 1/2 Hz or less can be achieved at or near the nominal load.
