Applicable Standard: IRC:83-2018 (Part III), MORTH Specifications, equivalent to EN 1337-7
Spherical bearings employ a curved PTFE-stainless steel interface machined to a spherical radius to accommodate rotation about any axis within a single component, along with a flat or curved sliding surface for translation, as covered under IRC:83-2018 (Part III). Cylindrical bearings are provided where rotation is required about a single axis only, typically for long-span and major river bridges.
