Product Description
Bridge Rubber Bearings Overview
Bridge rubber bearings, also known as elastomeric bearings, are essential components in modern bridge engineering. Positioned between the bridge superstructure (deck and beams) and substructure (piers and abutments), they provide controlled movement and flexibility to accommodate structural dynamics.
Key Applications
These bearings are specifically designed for bridges experiencing significant thermal expansion, seismic activity, and other structural movements. Their curved design and rotational capacity make them ideal for demanding bridge loading conditions.

Bearing Capacity Factors
- Rubber material crushing or cutting resistance
- Compression and shear deformation limits within allowable usage
- Prevention of support separation due to horizontal shear forces
Product Classification & Applications
Types Available
Round board type and rectangular plate type bearings
Application Scope
Standard bridge rubber bearings are suitable for spans under 30 meters with minimal displacement. Different shapes accommodate various bridge configurations: rectangular for orthobridges, curved/cylindrical for complex pier designs.
Key Design Features
- Curved/concave rubber element design for optimal performance
- Superior rotational capacity to accommodate bridge movement
- Pivoting action to handle changing load directions
- Accommodates bridge deformation and structural dynamics
Installation & Maintenance
Proper sizing, installation, and regular maintenance are essential for ensuring long-term structural integrity and safety of bridge systems.
