The AMC-MECANOCAUCHO® Vibrabsorber Spring Isolator with Adjustable Viscous Damping combines a steel spring with an integrated viscous damper, providing effective low-frequency vibration isolation together with precise control of suspended system movement.
The damper incorporates a chamber containing a thermally stable viscous fluid and a specially designed piston that allows mechanical adjustment of the fluid passage. By varying this opening, the fluid flow through the piston can be controlled, allowing the damping level to be adjusted according to the requirements of the installation.
This design allows the damping to be mechanically adjusted without changing the spring or replacing the damper, making it easier to optimize the dynamic behavior of the equipment after installation.
A rubber-to-metal bonded membrane ensures sealing of the chamber and prevents fluid leakage. The Sylomer® base complements the spring by improving high-frequency vibration isolation.
The spring isolator can also be precompressed using tie rods, facilitating installation or replacement without having to lift the machine.

This anti vibration mount incorporates Sylomer® buffers to limit the maximum vertical displacement of the suspended equipment.
Furthermore, the base of the spring includes a Sylomer® layer to reduce the transmission of high frequency vibrations and structural borne noise that can be transmitted through the coil springs.
This Vibrabsorber anti vibration mount is tailored for each application, and their static stiffness and minimum and maximum dynamic stiffness and loss angle at each amplitude can be set to reach the optimum values for the application.
