Spherical Bridge Bearing

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:

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.
