Flexible support ring maintaining the link between pipe and structure providing vibration isolation and protection against shock.
Pipe isolators
Natural frequencies under nominal load:
– axial: 10 to 30 Hz
– radial: 15 to 40 Hz
Maximum displacement in axial shock: ± 5 mm
Temperature range: 0 to 175° C

These assemblies can withstand high compression loads (along Oz): up to1,000 tons/sq.meter.
They can absorb shear deformation (along Ox and Oy) of 50 to 100% of their height.
Cylindrical or annular type assemblies can also withstand torsional displacement around axis Oz.
In rotation around axes Oy and Ox, these mountings enable angular or low amplitude rotation errors (approximately 1°).

These mountings were developed to handle small loads under large deflection (75 mm) and provide a low vibration transmission over a wide frequency range (up to 500 Hz).
The system developed provides this dual function effectively and without compromise.

Laminated BUSHES use the same principle as other laminated bearings. Importance is primarily given to radial load capability along Ox and Oy which may be up to 100 tons.
Movement is allowed around an axis Oz or a centre of rotation O. Angular deflection is in the order of 30°.

Models are available in different elastomers: silicon, fireproofed silicon, fluorosilicon or neoprene, to meet the requirements of the main aeronautics standards (FAR 25 – AIR 7304 – MIL STD 810 – C 172 C -MAR 508 s.o.).
Covering a natural frequency range of 15 to 50 Hz, their applications range from vibration isolation to shock-protection of electronic apparatus and also aircraft fuselage and helicopter cockpit mountings.
