Kga
with multiaxial displacement
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.
