General product description

Description FAEBI®-HD

FAEBI®-HD – rubber air spring isolator with adjustable damping

The combined rubber-air spring isolator FAEBI®-HD with adjustable damping comprises of an elastomer metal bonding with reinforced side wall and a two-chamber system. To achieve the greatest possible damping effect the interior of the air spring is divided into two air chambers connected by an air hose (load and damping volume). An adjustable throttle valve is used to set the flow cross section to the desired damping effect from the outside. The significantly higher damping effect compared to a single chamber system (FAEBI®) reduces the resonance amplification substantially and the machine movements fade noticeably faster. The increased energy absorption also has a positive effect on the manufactured goods and on machine and tool wear.

Please contact us, we would be happy to advise you.

Technical Data and Variants

Variant selection

Please select a suitable rubber air spring so that the maximum load (sum of static and dynamic load) is not exceeded
Please get in touch, we would be happy to assist you in selecting the most suitable elements.

Notes on FAEBI®-HD variants
  • If the bottom edge of the machine does not completely cover the diameter (∅ D) of the rubber air spring, we recommend the use of our special cover (see “Accessories” section for the individual air spring types).
  • Permissible temperature range: -20 °C to +60 °C
  • The elements are attached to the holes provided on the machine using the bolts supplied. Anchoring to the floor is usually not necessary.
  • Please bolt in by hand only, do not use a wrench! Please also fasten the corresponding nut with low torque only.
  • The machine is placed on the deflated element, which is then inflated in stages using the standard valve until dimension H (= working height) is reached. The maximum specified air pressure must also not be exceeded!
  • Ventilation and venting may only take place under load (please observe max. permissible pressure)!
  • Up to +/-5 mm are available for levelling.

FAEBI® HD pressure control

Pressure control

The Bilz pressure control is the ideal addition to applications that do not need automatic level control.
Instead of filling the air springs manually, they are connected to a constant compressed air supply. The working height of the individual insulators can each be individually set with one pressure regulator.

Applications

  • Applications with a constant centre of gravity during the production/testing process (no moving machine components, workpieces, etc., steady masses).
  • Difficult to access systems, where the manual checking of air pressure in the air springs is impeded.


Advantages of FAEBI® pressure control

  • Simple and precise setting of the required pressure for each air spring or control group
  • Low maintenance
  • Manometer for continuous pressure indication
  • Upstream particle filter and water trapCan be configured for any number of air springs or control groups

FAEBI® HD mechanical pneumatic level control MPN-LCV

Mechanical pneumatic level control MPN-LCV

The mechanical pneumatic level control MPN-LCV with our robust LCV proportional valves is a simple but effective solution to prevent tilting as a result of load changes. The target level is adjusted by turning the knurled adjustment ring and is maintained with an accuracy of ± 1/10 mm.
Item no. 61-0103

FAEBI® HD protective cover

Protective cover

If the surface of the FAEBI®-HD element is not completely covered by the bottom edge of the machine or the installation surface, an appropriate cover is required to ensure sufficient load distribution across the air spring. A hood will also provide protection from external damage.

Material
Steel sheet (primed black)
