About Bridge Bearing
Our offered PTFE Bridge Bearing is structural equipment and device which is installed between bridge substructure and superstructure to transfer the applied load. Further, these bearings make rooms for relative movements between superstructure and substructure, for example rotation movements and translational movements in horizontal and transverse direction. Our provided bridge bearing is made under the guidance of our expert professionals by using latest technologies keeping in mind the set quality norms. This PTFE Bridge Bearing is checked by our quality controller on different quality parameters before delivering to our valued customer end.

Precision Engineering for Critical InfrastructureOur bridge bearings are meticulously crafted to provide reliable load transfer and movement accommodation in both longitudinal and transverse directions. The elastomeric or steel composite structures comply with global standards such as IS:3400, BS:5400, and AASHTO. Each bearing is tested for hardness, shear modulus, and compression set, ensuring robust performance over time, even under fluctuating temperatures ranging from -40C to +70C.
Versatile Applications and CustomizationThese bearings are suitable for a wide range of structureshighways, flyovers, railways, metro bridges, and viaducts. The product is available in rectangular, circular, or custom shapes and sizes to match unique design challenges. With options for plate-mounted or plain installation and precision ratings specific to industry standards, they seamlessly integrate into new builds, retrofits, or ongoing bridge maintenance.
FAQs of Bridge Bearing:
Q: How are bridge bearings selected for different bridge types and projects?
A: Bridge bearings are chosen based on design standards such as IS:3400, BS:5400, AASHTO, and IRC:83 PART II, as well as factors like load capacity, expected movements (transverse and longitudinal), environmental conditions, and application (highway, metro, railway, etc.). Custom shapes and sizes are available to ensure compatibility with the specific bridge design.
Q: What are the advantages of using elastomeric or steel composite bridge bearings?
A: Elastomeric and steel composite bridge bearings offer excellent flexibility and load distribution, accommodate structural movements, absorb shock, and are highly resistant to harsh temperatures and weather. Their durability and low maintenance requirements make them ideal for modern infrastructure.
Q: Where can these bridge bearings be installed, and what are their typical uses?
A: These bearings are used in a variety of structures such as highways, railway and metro bridges, flyovers, and viaducts. They serve a critical role in transferring loads from the superstructure to the substructure while allowing necessary movements caused by thermal expansion, traffic loads, or seismic activity.
Q: What procedures are involved in manufacturing and quality assurance of bridge bearings?
A: Manufacturing follows established standards (IS:3400/BS:5400/ASTM D 4014), starting with raw material selection, precision engineering, and reinforced steel insertion. Each bearing is rigorously tested for hardness, shear modulus, compression, and environmental exposure to ensure quality and compliance.
Q: How does the bearing accommodate movement and resist environmental factors?
A: Bridge bearings are engineered to accommodate both longitudinal and transverse movements. With material hardness of 60 5 Shore A and a shear modulus of 0.9 0.1 MPa, they adapt to dynamic loads and temperature variations (-40C to +70C). Weather-resistant coatings on exposed steel parts further enhance durability.
Q: What are the customization options available for bridge bearings?
A: Customization includes shape (rectangular, circular, or as required), size (bore, outside/inside diameter), thickness (50300 mm or tailored), and mounting type (plate mounted or plain). The finish and load capacity (up to 1000 tons) can also be specified to match your project needs.
