DESCRIPTION
Metallic cushions are made from drawn, woven stainless steel wire that is compressed into a
geometric shape.
The Vibrachoc range has more than 1000 standard metallic cushions of various sizes and
characteristics.
As metallic cushions are easy to create, custom shapes and characte-ristics can be developed and
produced on request.

APPLICATIONS
Standard or custom metallic cushions can be used for many industrial applications because they are
naturally resistant to grease, oil, water, etc and withstand temperatures from - 70°C to + 300°C.
The static stiffness of the metallic cushion ensures progressive stiffening and maintains a constant
natural frequency for a very wide range of loads within a small space.
Their natural frequency of between 12 and 25 Hz and damping of 15 to 20% make them suitable for
mounting rotating machines with a rotation speed over 2000 rpm.
