Brige Pot Bearing

Shuanglin pot bearings handle massive vertical loads while permitting large horizontal movements and rotations. The elastomeric pad confined in steel transfers forces while allowing multi-directional flexibility.

Available in fixed, guided, or free-sliding designs for curved/skewed bridges and space constraints. Constructed to AASHTO/EN 1337 standards with high vertical stiffness, low rotational resistance, and smooth PTFE sliding surfaces.

Reliable force transfer and structural flexibility for high loads, frequent movements, or unique bridge demands. Proven solutions for your most challenging projects.

  • Vertical support up to 5000 kN.
  • Minimal lateral movement ensures stability.
  • Designed for structures with low expansion.
Free Sliding Pot Bearing

Free Sliding Pot Bearing

The JPZ (II) pot-type rubber bearings stand out due to their dovetail structure. By connecting the upper support plate with shear keys, these bearings optimize load distribution and reduce overall weight.
  • JPZ (II) cuts anchor shear by 20%, improving load distribution.
  • Mid-rail enhances sliding, cuts weight by 15%.
  • Three settings resist horizontal forces effectively.
  • UHMWPE boosts lifespan by 30%.

Structure

The design and materials of pot bearings follow standards like EN 1337, BS 5400, and AASHTO to ensure their load-bearing capacity, rotation capability, displacement capacity, and durability.
  • Top Plate:

Material: High-strength steel (ASTM A36)

Function: Distributes loads uniformly, provides a stable surface.

    1. Stainless Steel Plate:
      1. PTFE Sheet:
        • Material: Polytetrafluoroethylene (PTFE) for low friction. ASTM D4894
        • Function: Enables smooth sliding, minimizes wear.
      2. Brass Sealing Ring
        • Material: Brass
        • Function: Seals the elastomeric disc laterally to prevent extrusion
      3. Elastomeric Pad:
Material: Elastomer (e.g., natural rubber, neoprene) EN 1337, BS 5400, AASHTOFunction: Deforms to accommodate rotational movements while transferring vertical load
      1. Steel Pot:
        • Material: High-strength steel alloy. ASTM A709
        • Function: Transfers vertical loads, ensures stability.

      2. Piston Plate

        • Material: Stainless steel or carbon steel
        • Function: Transfers vertical load from the top plate to the elastomeric disc

FAQ

Under normal conditions and with proper maintenance, our elastomeric 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.
