Unlocking Bridge Longevity with Elastomeric Bearings

Elastomeric bearings are the unsung heroes of modern bridges, playing a crucial role in ensuring structural integrity, reducing maintenance costs, and extending the lifespan of these critical infrastructure assets. As a leading manufacturer of elastomeric bearings, we're here to provide you with the insights you need to harness the power of these essential components.

Basic Concepts of Elastomeric Bearings in Bridges

Elastomeric bearings are flexible, rubber-like devices that are placed between the bridge deck and the supporting structure. They act as shock absorbers, isolating the bridge from seismic forces, temperature changes, and other dynamic loads. This unique ability prolongs the bridge's lifespan, reducing the need for costly repairs and replacements.

Elastomeric Bearing Type	Description
Plain Elastomeric Bearings	Basic pads with no internal reinforcement
Laminated Elastomeric Bearings	Layers of elastomer and steel plates
Reinforced Elastomeric Bearings	Internal steel rods or plates to enhance strength

Elastomeric Bearing Properties	Benefits
Flexibility	Absorbs dynamic loads and reduces stress on the bridge structure
Durability	Resistant to environmental factors, ensuring long-term performance
Corrosion Resistance	Suitable for use in areas with harsh weather conditions

Advanced Features of Elastomeric Bearings

Our elastomeric bearings are engineered with advanced features to meet the demands of modern bridge design. These include:

Seismic Isolation: Our bearings are designed to withstand lateral forces during earthquakes, protecting the bridge from damage.
