Lead Rubber Bearings
Lead Rubber Bearings represent the gold standard in seismic isolation technology, combining laminated rubber with a central lead core for maximum energy dissipation. These proven bearings provide superior protection for nuclear facilities, emergency response centers, and critical transportation infrastructure in high-risk seismic zones.
Engineered for Excellence in Seismic Isolation and Energy Dissipation
Lead rubber bearings are engineered for excellence, providing superior seismic isolation. Their unique design allows for controlled deformation, ensuring structures remain safe during seismic events. Experience peace of mind knowing your infrastructure is protected with cutting-edge technology.
Features of Our Lead Rubber Bearings
Suggested use for bridges and buildings located in medium and high level earthquake zones
In these isolators, rubber elasticity provides re-centering capacity while the lead core, stressed beyond yield point, delivers energy dissipation. Combining alternating rubber/steel layers with lead cores creates a structure with high vertical stiffness but low horizontal stiffness. This dual-property design enables substantial vertical load-bearing while allowing horizontal displacement. The lead core's unique ability to re-crystallize after yielding permits virtually unlimited yield cycles, making these bearings exceptionally durable for seismic protection.
Delivering Superior Seismic Isolation with Proven Performance
CECO's Lead Rubber Bearings represent the gold standard in seismic isolation technology, reducing structural acceleration by up to 85% during major seismic events while maintaining vertical load capacity. These sophisticated bearings combine the stability of laminated rubber with the energy dissipation capabilities of a central lead core, creating a system that has protected critical infrastructure worldwide for decades with unmatched reliability.
Multi-Protection
Safeguard against earthquakes, aftershocks, and ground motion through an engineered lead core that absorbs and converts seismic energy into heat.
Vertical Stability
Maintain consistent vertical load support even during extreme horizontal displacements, ensuring structural integrity throughout seismic events.
