FAEBI®-HD rubber air springs

FAEBI®-HD – rubber air springs insulator with adjustable damping

The combined rubber-air spring insulator 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 substancially absorption also has a positive effect on the manufactured goods and on machine and tool wear.

Benefits: In comparison to viscous damping, air damping is absolutely free of wear and maintenance-free and the damping factor can be easily adjusted from outside.

Pressure control

Druckregelung

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 the FAEBI® pressure control

  • Simple and precise setting of the required pressure for each air spring or control group.
  • Maintenance free
  • Manometer for continuous pressure indication
  • Upstream particle filter and water trap
  • Can be configured for any number of air springs or control
    groups

Mechanical-pneumatic level control MPN-LCVFaebi Niveauregelung Ventil

The mechanical-pneumatic level control (MPN) with our robust proportional valve LVC represents a simple but effective solution for preventing skew positions resulting from load changes. A plunger continuously probes the level and the position of the plunger is transmitted to a slide valve. The air spring is either pressurized or the internal pressure is vented in accordance with the position of the plunger. The adjustable target level is
maintained within an accuracy of ± 1/10 mm. In principle three control valves are used, that optionally have an upstream air maintenance unit for conditioning the pneumatic air
supply, limiting the system pressure to 6 bar, removing accumulated condensate and filtering out solid particles (rust and dust).

Very robust galvanised proportional valve. Level accuracy is approximately ± 1/10 mm.

Protective hood

Abdeckhaube für FAEBI Gummi-Luftfeder Isolator

If the contact surface of the FAEBI® element (see Type series FAEBI® or FAEBI®-HD) is not completely covered by the bottom edge of the machine, then an appropriate hood is required to ensure the sufficient load distribution across the air spring. A hood will also provide protection from external damage.
Material: Steel sheet (primed black)
The protective hood is also available in stainless steel on request.
