Almost every highway and bridge in China is using our Elastomeric bridge bearing.

Description of Plate Type Elastomeric bridge bearing:

Natural Elastomeric bridge bearing generally consists or interleaving layers of rubber bonded sandwich fashion to steel plates. The whole unit is covered with rubber to afford weather protection.

A bridge basically consists of bridge deck supported by piers. In order to avoid over stressing and damage by movements of vehicle and loading to the piers, Elastomeric bridge bearings are used to accommodate these movements so as to reduce the reaction forces and bending movement to within the safety limits of structure. Natural Rubber is an ideal engineering material for bridge bearings as it is highly elastic and sufficiently soft to accommodate these movements without transmitting harmful stress and also it can absorb and isolate energies from impacts and vibrations.

Features of Plate Type Elastomeric bridge bearing:

1. Performs required functions efficiently

2. Totally maintenance free

3. No moving parts and therefore no wear & tear

4. No corrosion

5. Absorbs shocks & vibrations

6. Cheaper than mechanical bearings

7. Simple to install

8. Capable to accommodate small irregularities in the loading surface.

9. No static friction to overcome.

Advantages of Plate Type Elastomeric bridge bearing:

Plate Type Elastomeric bridge bearing effectively releases the stress on the bridge and has excellent rotation in all the directions and movements. The inserted metal plates restrict the rubber expansion on the sides and improve the resistance to load on the bridge as the elasticity of rubber absorbs shock well and lengthens the natural period of stress. Another advantage of Plate Type Elastomeric bridge bearing is the robustness and corrosion free nature of these products, ease and convenience of installation, long service life and customized size to suit the bridge design.
