Spherical Bridge Bearings

Spherical Bridge Bearings are specialized structural bearings designed to support heavy vertical loads while allowing smooth rotational and limited translational movements in bridges and large-span structures. Composed of a precision-machined steel spherical surface combined with PTFE or composite sliding materials, these bearings efficiently transfer loads from the superstructure to the substructure while accommodating thermal expansion, rotational deformation, and seismic forces. Known for their high load-bearing capacity, excellent durability, and resistance to extreme weather and corrosion, spherical bridge bearings are widely used in highway bridges, railway bridges, viaducts, and large concrete or steel structures, ensuring structural safety, extended service life, and reduced maintenance requirements.

Aohong, a professional manufacturer of Spherical Bridge Bearings, provides high-performance bearings designed to withstand extreme vertical, horizontal, and lateral loads while allowing smooth rotational movement. These Rubber Bearings are widely used in highway bridges, railway bridges, steel structures, and other large-span infrastructure where high load capacity and controlled structural displacement are required. Engineered with advanced materials and tested to international standards, our bearings ensure excellent durability, minimal maintenance, and long service life.

Structure and Design of Spherical Bridge Bearings

Spherical bridge bearings are composed of a concave steel plate, convex stainless-steel sliding plate, and PTFE sliding layer with a special lubricant to ensure permanent low-friction performance. The stainless steel convex plate allows free rotation, while the recessed PTFE sheet accommodates thermal expansion and structural movement. This design ensures stable load transfer from the superstructure to the substructure, making them ideal for bridges with large turning angles, skewed structures, or high torsional forces.
