Laminated mountings
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°).

They allow to limit the reactions at the moment of the shock.
The permitted deflection (40 to 50 mm) of the suspended mass in relation to the mounting base limits reaction under shock.No efficient vibration protection is offerred during shock.

Laminated bushes
Laminated BUSHES use the same principle as other laminated bearings.
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°.
