Reliable, durable, and customizable engineering rubber products and bridge components for infrastructure projects worldwide.
Spherical Bridge Bearing is a bridge support device designed with a spherical rotation structure. It mainly consists of upper and lower bearing plates, spherical sliding surfaces, PTFE sliding plates and other components.The spherical surface allows angular rotation of bridge structures under loads, effectively accommodating deformation, rotation and displacement caused by temperature variation, structural deflection and dynamic loads.With high load capacity, smooth rotation performance, compact structure and long service life, Spherical Bridge Bearings are widely used in highway bridges, railway bridges, long-span bridges and other major infrastructure projects.
