Applicable Standard: IRC:83-2018 (Part III), MORTH Specifications, equivalent to EN 1337-5 / EN 1337-8
Pot bearings, manufactured as per IRC:83-2018 (Part III), confine an elastomeric disc within a machined steel pot which acts as a near-incompressible medium to provide rotation, while a PTFE-stainless steel sliding interface accommodates translation. Pin bearings and metallic guided bearings are provided where movement is to be restrained in a chosen direction while permitting free rotation, as commonly adopted for major bridges on National Highways and railway girder bridges.
