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.
