SPHERICAL BEARINGS

Spherical bearings are built to withstand big loads and simultaneous large deformation in any direction, while allowing for large rotations (>0.02 rad) in any of the bearing’s axes. Rotation capacity is obtained by coupling an internal median plate machined as a spherical surface and a complementary plate where a sheet of a low friction material (for example PTFE) is recessed. Movement capacity is obtained by coupling a sheet of a low friction material (for example PTFE) with a stainless-steel surface. Depending on the configuration, they can accommodate horizontal loads as well as movements in longitudinal or/and transversal directions.

This kind of bearing can withstand vertical loads of up to 100.000 kN.

The reference European Standard Code is EN 1337-7.
