Spherical bridge bearings, composed of precision-machined steel plates with spherical concave and convex surfaces, provide flexible movements and rotations between the superstructure and supporting structures to transfer whether horizontal or vertical force safely.

Features:

A diagram of a guided spherical bridge bearing
Spherical bridge bearing - guided type
Allows for large displacement.
Accommodate larger rotations than pot bearing in excess of +/- 0.03 radians.
Unlimited movement capability in any directions.
Excellent self-alignment capability.
Minimum sliding friction coefficient.
Dimpled PTFE disc is fitted in 1/2 depth of the concave steel plate for higher load bearing capacity.
PTEF disc with cavities for containing lubricant to reduce sliding friction.
Complying with BS EN-1337, KS4424, AASHO, ISO or other custom standards.
Easy installation.
Low cost maintenance.
Applications:

Ideal for structures with bearings of larges turning angles.
Bridges with big torsions.
Bridges in low temperatures lower than -30℃.
Wide and curved bridges.
