Product Description

Product Description

Description of pot bridge bearing:

Pot bridge bearing, with elastomeric bearing pad fitted inside of steel plate, is the widest used type for transferring vertical or horizontal loads from superstructure to the pier as well as allowing rotations on any axis. Meanwhile, it's capable to accommodate horizontal displacements of superstructure taking advantages of the reduced friction coefficient between stainless steel panels and a layer of PTFE.

 

Components of pot bridge bearing:
 

Steel top plates - capable to accommodate longitudinal or transverse sliding movements of the superstructure.Stainless steel panels & PTFE - reduce the friction resistance as well as horizontal force.Steel piston & internal brass sealing ring - protect the elastomer pad from extrusion.Elastomeric pad - behaves like a fluid under high pressure and allows higher working pressure with reduced dimensions.As your request, external rings can be supplied to make sure that the gap between piston and steel pot is free of moisture and debris.

Features

Features of pot bridge bearing:

With low-profile yet high loading capability over 50,000 KN.Maximized shearing strength of elastomer pad through the method of encasing it in the steel pot.Allow for large rotations ranging from 0 to 0.03 rad.Low friction coefficient between 1% and 3%.Excellent fatigue, impact and aging resistance of the layer of PTFE.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).Easy and quick to install.Easy to maintain and replace the worn out and broken part.Complying with BS EN-1337, KS4424, AASHO, ISO or other custom standards.

 

Application

 

Applications of pot bridge bearing:

Incrementally launched bridges.Curved or skewed bridges.Structures with rotations in various directions.Structures using the incremental launching methods.Highways and railways, etc.

                    Guided sliding pot bearing is used for bridge.                                                           Pot bearings are used for highway.

Types of pot bridge bearing :

According to horizontal movements, pot bridge bearings can be classified into three types as follows:

Free sliding pot bearing is able to slid and rotate in all directions without any restraints.Fixed pot bearing restrains movements in all directions. Under loads, the elastomeric bearing pad behaves likes an incompressible confined fluid which enables the rotations on any axis. Edge & center guided bearing features fitted edge or center guide to limit the bearing's movements. It allows for movements in longitudinal or transversal directions.
