Product Description

Elastomeric bearing pads for bridges are fabricated of natural rubber or neoprene.

Designed and sized to meet the needs of your structure, these bearings are rigid enough to transmit the necessary loads and flexible enough to permit the rotation and movement required by the structure.

They can also be used for vibration and earthquake motion control applications.
