Elastomeric Bridge Bearing

About Elastomeric Bridge Bearing

Sandhyaflex Elastomeric Bridge Bearing is a structural support component used mainly in bridge construction to transfer loads safely while allowing controlled movement between the bridge deck and substructure.

What is Sandhyaflex Elastomeric Bridge Bearing?

It is a rubber-based (elastomeric) bearing pad, often reinforced with steel laminates, designed to:

• Support heavy loads from the bridge

• Allow horizontal & rotational movement

• Absorb vibrations, thermal expansion, and contraction

These bearings are widely used in:

• Bridges

• Flyovers

• Buildings

• Stadiums & heavy structures (Sandhya Flex)

Key Features

• High flexibility accommodates multi-directional movement

• Strong load-bearing capacity typically up to 1020 MPa design loads (sandhyaenterprises.co.in)

• Durability long service life (around 15 years warranty) (Sandhya Flex)

• Weather & chemical resistance

• Low maintenance

• Easy installation

Construction & Material

• Made from high-grade rubber (Neoprene/CR)

• Often laminated with steel plates for strength

• Designed as per standards like:

  • IRC 83 (Part II)

  • MoRTH specifications (Sandhya Enterprises)

Typical Specifications

• Thickness: 22 mm to 144 mm

• Size: Custom (e.g., 500 400 96 mm) (Sandhya Flex)

• Tensile strength: 17 MPa (Sandhya Enterprises)

• Shear modulus: 5 MPa (Sandhya Enterprises)

• Material: Rubber with/without MS steel plates

Working Principle

• Vertical load compresses rubber layers

• Horizontal movement absorbed by shear deformation

• Rotation accommodated due to flexibility

This eliminates the need for mechanical moving parts and reduces maintenance.

Types Available (Sandhyaflex)

• Plain Elastomeric Bearings

• Laminated Elastomeric Bearings

• Neoprene Bridge Bearings

• Heavy-duty bearings

• Steel-reinforced bearings (Sandhya Enterprises)

Advantages

• Cost-effective compared to mechanical bearings

• No lubrication required

• High shock and vibration absorption

• Long service life

• Suitable for both small and large bridges
