Round Laminated Elastomeric Bearing Pads are structural support elements used in bridges and buildings to absorb vertical loads and accommodate horizontal movements such as thermal expansion, seismic activity, and wind-induced shifts. These bearings consist of multiple layers of natural or neoprene rubber bonded with internal steel plates, providing a balance of flexibility and strength. Their circular design ensures even load distribution and allows for efficient rotational and shear deformation, reducing stress on supporting structures. Widely used in highway bridges, precast concrete structures, and seismic isolation systems, these pads offer long-term durability, resistance to aging, and consistent performance under varied environmental and load conditions.
Aohong offers premium Round Laminated Elastomeric Bearing Pads, meticulously engineered for structural load transfer and movement accommodation in bridges and civil infrastructure. Designed with alternating layers of high-grade rubber and steel laminates, these pads provide a balance of rigidity and flexibility required for demanding environments. Our offerings include Natural Rubber (NR) and Chloroprene Rubber (CR) variants, with optional PTFE sliding surfaces available for enhanced seismic or thermal displacement performance.
Structure
Rubber Layers: Composed of multiple sheets of NR or CR elastomer, vulcanized together for uniform deflection and high elasticity.
Steel Shims: Typically 2–5 galvanized or stainless-steel plates, improving vertical load-bearing capacity and dimensional stability.
Bonding Process: Industrial-grade adhesive and vulcanization combine rubber and steel layers into a monolithic pad.
PTFE Option: 2 mm to 3 mm PTFE sheet laminated to the top surface in sliding pad versions, enabling low-friction lateral movement.
Sealing & Finishes: External rubber covers resist ozone, UV light, and moisture for long-term durability.
