Natural Rubber Bearings (NRB) are structural isolation devices designed to transfer vertical loads while allowing controlled horizontal movement and rotation, making them widely used in highway bridges, railway bridges, and building structures. Composed of multiple layers of natural rubber bonded with steel reinforcement plates, NRBs provide excellent elasticity, high vertical stiffness, and good shear deformation capacity to accommodate thermal expansion, structural rotation, and minor vibrations. Known for their durability, maintenance-free design, and cost-effectiveness, natural rubber bearings effectively reduce dynamic loads, improve structural stress distribution, and are suitable for standard temperature conditions in bridges, precast concrete slabs, and other civil engineering applications.
