About Elastomeric Bearings
Elastomeric bearings are laminated structural bearings manufactured from elastomeric rubber layers sometimes reinforced with internal steel plates. They are designed to safely transfer loads while allowing controlled movement and rotation between structural elements.

Typical Elastomeric Bearing Configurations
Laminated Elastomeric Bearing (Standard)
A multi-layer bearing consisting of alternating elastomer layers and internal steel laminates, bonded and vulcanized as a single unit.
Function:
- Transfers vertical loads safely
- Allows controlled horizontal movement
- Accommodates rotation at supports
Common Uses:
Bridges, podium slabs, transfer beams, industrial structures
Reinforced / High-Load Elastomeric Bearings
Designed for higher vertical loads and reduced deformation, typically with increased laminate thickness or modified elastomer compounds.
Function:
- Eliminates the transmission of vibration through the building structures
- Supports heavy superstructures
- Controls shear strain
- Improves long-term creep resistance
Seismic & Movement-Control Bearings
Specially engineered elastomeric bearings designed to perform under seismic, dynamic, or high-movement conditions.
Function:
- Dissipates energy
- Reduces force transfer to structure
- Protects columns, piers, and foundations
How Elastomeric Bearings Work (Simplified)
Elastomeric bearings work by:
- Compressing vertically under load
- Shearing horizontally to allow movement
- Rotating naturally without mechanical parts
This eliminates the need for sliding components, lubrication, or regular maintenance—making them ideal for long-life infrastructure projects.
Frequently Asked Questions (FAQ)
What is an elastomeric bearing used for?
lastomeric bearings are used to transfer loads, reduce vibration and noise while allowing movement and rotation between structural elements. They are most commonly installed between bridge decks and piers, columns and foundations, beams, podium slabs, or heavy industrial structures and foundations.
When should elastomeric bearings be specified?
They should be specified whenever a structure must accommodate:
- Thermal expansion and contraction
- Vibration isolation is required
- Differential settlement
- Rotational movement
- Seismic or dynamic effects
Early specification during the design stage significantly reduces long-term structural risk.
What materials are used in elastomeric bearings?
Most elastomeric bearings are manufactured from:
- Neoprene rubber or natural rubber
- Internal steel laminates for load control
The elastomer compound is selected based on environment, load, movement, and durability requirements.
Are elastomeric bearings maintenance-free?
Yes. Properly designed and installed elastomeric bearings are maintenance-free and have a long service life, often exceeding 50 years when correctly specified.
What standards govern elastomeric bearing design?
Elastomeric bearings are typically designed in accordance with:
- AASHTO
- BS / EN standards
- Project-specific authority requirements
Unigroup ensures full compliance during design review and supply.
How do I choose the correct elastomeric bearing?
Correct selection depends on:
- Vertical load
- Horizontal load
- Required movement
- Rotation capacity
- Environmental exposure
Unigroup provides engineering-led consultation to ensure the bearing is correctly sized and specified.
Can elastomeric bearings be used in seismic zones?
Yes. Elastomeric bearings can be engineered for seismic isolation and energy dissipation, significantly reducing forces transmitted to the structure.
Do you provide calculations and technical submittals?
Yes. For every project, we support with:
- Load and movement calculations
- Datasheets
- Technical submittals
- Installation guidelines
In collaboration with Farrat, all solutions are project specific.
