Oil platform anchoring points.
Helicopter rotor hub bearings.
Piping swivel joints.
Laminated bearings
Conical (fig. 1) or spherical (fig. 2) units are used to absorb very high axial loads of up to150 tons.
Angular movement around an axis (Oz in the case of the conical bearing) or a centre of rotation (O in the case of the spherical bearing) are in the order of ± 10°.

Laminated mountings
These assemblies can withstand high compression loads.
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°).
