Seismic Isolation Basin Fixed Bridge Pot Bearings

Brief Introduction
Pot bearings ensure the transfer of loads between a structure's superstructure and its sub-structure. Meanwhile they can accommodate rotation and movements of the superstructure. AVIDA POT bearings are generally suitable for the use in any type of structure, and can be subjected to low or high loading and frequent movements and rotation.Pot bearings are designed and manufactured acc. to customer requirements, in accordance with relevant standards such as EN 1337, AASHTO, BS5400 or AS 5100.a.Inner StructureRubber Physical&Mechanical Properties

Features1, With low-profile yet high loading capability over 50,000 KN.
2, Maximized shearing strength of elastomer pad through the method of encasing it in the steel pot.
3, Allow for large rotations ranging from 0 to 0.03 rad.
4, Low friction coefficient between 1% and 3%.
5, Excellent fatigue, impact and aging resistance of the layer of PTFE.
6, All the metallic parts are protected against corrosion by galvanization and epoxy painting according to EN 1337-9 (other protective coatings are available as your requirements).
7, Complying with BS EN-1337, KS4424, AASHO, ISO or other custom standards.Product Show
