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°).

– Natural frequency (vertical and lateral) under nominal load: 4 to 5.5 Hz.
– Maximum displacement under shock:75 mm all in directions.
– Mechanical strength: 30 g

The main role of these mountings is to isolate vibration. A snubber system limits the movement of the suspended mass (10 mm), however the loads developed in this case, are high.
A wide load range from 5 to 320 N depending upon the application.

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.
