Product Description

Product Description

    Bridge rubber bearing is a critical seismic isolation and energy dissipation device for bridge structures, mainly installed between the superstructure and piers or abutments. The product is manufactured through high-temperature vulcanization bonding of premium rubber and steel plates, featuring strong load-bearing capacity, excellent deformation performance, and outstanding durability.

    We can provide international certificates including ISO, CE, and RoHS. It can effectively transfer and distribute loads from the superstructure while accommodating horizontal displacements and rotations caused by temperature changes and loading, significantly reducing damage to bridges from earthquakes and other external forces, extending service life, and is widely used in various bridge projects including highway bridges, railway bridges, and urban viaducts.

Material

Bridge rubber bearings are typically made from high-strength natural rubber or synthetic rubber materials. These materials offer excellent compressive strength and weather resistance, as well as good elasticity and fatigue resistance, allowing them to withstand various mechanical forces experienced by bridges during use.

Function
The primary function of the bridge rubber bearing is to support vertical and horizontal loads of the bridge while allowing it to rotate freely during movement and deformation. It effectively reduces stresses caused by foundation settlement and temperature changes, ensuring structural safety.

Product Features

• Excellent Elasticity: Appropriate vertical stiffness

• High Durability: Superior aging and fatigue resistance

• Easy Installation: Standardized design for convenient construction

• Low Maintenance: No special maintenance required during service life

• Cost-Effective: High performance-price ratio

Product Advantages

• Reliable Performance: Strictly tested and verified
• Long Service Life: Design service life up to 50 years
• Strong Adaptability: Suitable for various bridge structure types
• Mature Technology: Proven through years of engineering practice
• Comprehensive Service: Professional technical support
