with multiaxial displacement

Spherical bearings as per DIN EN 1337-7

Bearing with multiaxial displacement, displacement in both axes. The maximum vertical load transmission is 50 MN (V).

The importance of spherical bearings has grown in recent times. The hard, chromium-plated side of a convex dome sits in a concave shell which is lined with PTFE of a suitable quality for use in bridge bearings.

The dome also supports another PTFE element which is divided into chambers. Above this, there is a steel plate equipped with a sliding sheet via which the multidirectional movements of the bridge and the bearing forces are dissipated.
