Elastomeric Bearing Pad

1. Material Composition‌

Elastomeric Bearing Pads are engineered from ‌high-quality elastomers‌ (typically ‌chloroprene rubber‌ or ‌natural rubber‌) reinforced with layered steel and rubber. Key material advantages include:

• ‌Durability‌: Resistant to aging, ozone, and UV exposure.
• ‌Flexibility‌: Accommodates multi-directional movements (compression, shear, rotation).
• ‌Temperature Tolerance‌: Performs reliably in -40°C to +70°C environments.

‌2. Structural Design‌

The innovative layered structure ensures optimal load distribution and longevity:

• ‌Laminated Rubber Layers‌: Alternating rubber and steel/fiberglass plates (similar to ‌Laminated Rubber Bearings‌) enhance vertical stiffness while allowing horizontal flexibility.
• ‌Reinforced Edges‌: Prevents delamination under heavy loads.
• ‌Surface Grooves‌: Improves slip resistance and alignment during installation.

‌3. Key Applications‌

Elastomeric Bearing Pads are critical components in ‌Bridge Bearings‌ systems, widely used in:

• ‌Highway/Railway Bridges‌: Absorb vibrations and compensate for thermal expansion.
• ‌Seismic Isolation‌: Protect structures from earthquake forces (often paired with ‌Pot Bridge Bearings‌ for high-load scenarios).
• ‌Building Foundations‌: Reduce noise and stress in prefabricated structures.

‌4. Advantages Over Alternatives‌

Compared to traditional ‌Pot Bridge Bearings‌ (metal-centric) or plain ‌Laminated Rubber Bearings‌:

• ‌Low Maintenance‌: No lubrication or corrosion protection required.
• ‌Cost-Effective‌: Simplified installation and longer service life.
• ‌Adaptability‌: Suitable for both small-span bridges and complex seismic zones.

‌5. Technical Standards‌

Compliant with global certifications:

• ‌ASTM D4014‌ (Elastomeric Bridge Bearings)
• ‌EN 1337-3‌ (Structural Bearings – Elastomeric)
