Bridge bearings, seismic isolation bearings, rubber bearings, and bridge expansion joints are essential components in bridge construction, providing load transfer, movement accommodation, and structural protection. Bridge bearings, including elastomeric, pot, and spherical types, transfer loads between the superstructure and substructure while allowing rotation and displacement. Seismic isolation bearings, such as lead rubber and friction pendulum types, reduce earthquake forces and enhance structural resilience. Rubber bearings offer flexibility and vibration absorption, while bridge expansion joints accommodate thermal expansion, contraction, and movement between bridge sections. These products are widely used in highway bridges, railway viaducts, overpasses, and seismic-resistant infrastructure projects.
