Bridge Spherical Bearing

Spherical bearings offer reliable force transmission, flexible rotation, and adaptability to large angles. Ideal for projects with smooth rotation needs, they eliminate concerns about rubber aging, making them suitable for low-temperature applications.

Shuanglin fully complies with international standards： EN 1337 , AASHTO and China Standard.

Vertical Load Capacity: From 1000kN to 20000kN
Maximum Rotation Angle: 34’～69’
Maximum Displacement:
– Longitudinal (Bridge Direction): 50～150mm
– Transverse (Perpendicular to Bridge): 20mm
Friction Coefficient: f ≤ 0.05
Horizontal Load Capacity: 10% of the vertical load capacity

Types of Bridge Spherical Bearings

Fixed spherical bearing

Fixed Spherical Bearing

  • Strong wind and seismic resistance.
  • No rotation, only shear deformation.
  • Widely applicable to straight and inclined bridges.

Guided Spherical Bearing

  • Excellent horizontal displacement.
  • Horizontal rotation only, ideal for straight and inclined bridges.

Sliding Spherical Bearing

  • Rotates horizontally and vertically.
  • Well-suited for curved, sloped, and wide-span bridges.

Simplified Installation Guidelines of Bridge Spherical Bearing

  1. Upon delivery, ensure leveled bearings with tightened bolts to prevent rotation during transport.
  2. Before installation, inspect documentation. Do not disassemble or rotate components after unboxing.
  3. For bolted installations, adjust horizontal position using shims, ensuring a 20-50mm gap above the pier’s surface. Align with design and use epoxy mortar for support layers.
  4. In welded installations, accurately position and intermittently weld plates to embedded steel. Prevent burning of the bearing and concrete during welding.
  5. Ensure the height aligns with design. Maintain a smooth profile, with a max 2mm height difference at corners.
  6. After beam installation, remove connecting plates before prestressing to allow normal rotation.
  7. Post-removal, inspect for damages and promptly install dust covers.
  8. After one year, conduct a quality check, clear debris, and wipe stainless steel surfaces with cotton.

FAQ

Under normal conditions and with proper maintenance, our bridge spherical bearings have a service life that can exceed 50 years.

Our bearings are engineered with a focus on fatigue life under dynamic loads. The rubber compound and steel reinforcement layers are optimized to provide durability and resilience under heavy loads.

We conduct a range of tests, including compression, shear, and fatigue tests, to validate the performance of our bearings. We also perform finite element analysis (FEA) and other simulations to ensure that our bearings meet the required specifications.

Yes, we offer bearings that are designed to meet specific seismic design requirements, including those specified in AASHTO, EN, and other international standards.

Please provide us with the details of your project, including the number of bearings required, the dimensions, and any specific design requirements, and we will provide a detailed quote.

Absolutely, our team of engineers is available to provide technical advice and, if necessary, on-site support to ensure proper installation and alignment of the bearings.

Our standard lead time is approximately 4-6 weeks from the order confirmation. For urgent needs, we may be able to expedite production subject to availability.

We provide a certificate of original, test reports, and detailed installation instructions with each shipment.
