Elastomeric Bearing (Rubber Bearing)
PILLAR Thailand offers high-performance Laminated Elastomeric Bearings, precision-engineered and manufactured by PILLAR Taiwan. These bearings are designed to provide superior structural support and seismic isolation, ensuring the longevity of critical infrastructure projects across Southeast Asia.
Precision Engineering & Construction
Our bearings are designed to handle extreme vertical loads while maintaining horizontal flexibility.
-
Laminated Strength: Each unit is constructed with alternating layers of internal rubber and reinforced steel plates. This design significantly increases vertical stiffness, preventing excessive bulging under the weight of the structure.
-
Movement Accommodation: The internal steel laminates allow the bearing to support massive vertical pressure while simultaneously accommodating thermal expansion, rotation, and shear deformation.
Material Excellence: NR vs. CR
To meet diverse project specifications and environmental conditions, we offer two primary material formulations:
-
Natural Rubber (NR): Known for its high resilience and excellent physical properties, making it the standard for many structural bridge applications.
-
Neoprene (Chloroprene Rubber - CR): Specially formulated for projects requiring high resistance to oil, chemicals, and extreme atmospheric aging (ozone/UV).
Versatile Infrastructure Applications
PILLAR Taiwan’s elastomeric solutions are trusted for a wide range of seating and isolation requirements:
-
Infrastructure: Primary structural bearings for PCI Girders and Box Girders in highway and railway bridges.
-
Building Construction: Seismic isolation and load distribution for commercial and residential structures.
-
Industrial "Fab" Buildings: Specialized support for piping girders in high-tech manufacturing plants to isolate vibration and protect sensitive equipment.
Elastomeric Bearing Characteristic
-
Maintenance-Free Design: With no movable internal components, these bearings eliminate the need for lubrication and periodic servicing.
-
Environmental Resilience: * Corrosion & Chemical Resistance: Highly resistant to oil and harsh chemicals, ensuring long-term integrity in industrial zones.
-
Temperature Stability: Engineered to remain flexible without cracking in freezing conditions and offer high resistance to burning.
-
-
Superior Load & Movement Handling: * Low Creep & High Strength: Exceptional physical endurance under constant pressure.
-
Thermal Displacement: Efficiently compensates for structural expansion and contraction caused by temperature fluctuations.
-
Extreme Buffering: Acts as a high-performance shock absorber against dynamic loads.
-
-
Streamlined Installation: Lightweight and space-saving design reduces onsite labor costs and fits into compact structural footprints.
International Design Specifications
We ensure our products meet the highest global safety and quality standards. Our bearings can be custom-designed and tested to comply with:
-
