INFAB™ Foundation Isolation
|
In some applications, it is not feasible to mount a machine directly on vibration isolators. An integral part of most machine tool installations is a properly designed foundation which will meet the machine's support requirements. Isolating a vibration-sensitive or vibration-producing machine requires isolation of its support mass or foundation.
INFAB™ elastomeric (rubber) isolators provide low frequency isolation from induced shock and vibration for applications requiring support foundations and inertia blocks. INFAB™ isolation systems can be designed to have a natural frequency as low as 6.0 Hz.

A vibration site survey/analysis will determine the levels of vibration existing at your site, which is essential for proper vibration control recommendations to be made. Please contact Fabreeka's® Engineering Department for assistance with your particular application or if you would like information regarding a vibration site survey.

For applications requiring an alternative to the standard INFAB™ isolator sizes and characteristics, INFAB™ isolation panels can be designed to have natural frequencies from 6.0 Hz to 10.0 Hz (6% damping) by custom designing the physical size and thickness of the isolators. The panels are comprised of rubber INFAB™ isolators secured to a rigid substrate, which is used as the forming for the bottom of the concrete foundation. The panel feature allows for greater flexibility in the structural support design of the foundation and a less costly installation.
