with uniaxial displacement

Spherical bearings as per DIN EN 1337-7

Bearing with uniaxial displacement, transfers horizontal forces in one axis. 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 bearing forces are dissipated.

The longitudinal movement of the bridge is controlled by means of the lateral guide element.
