Natural Rubber Bearing Pads
Hanna Rubber Company’s premium natural rubber (polyisoprene) bearing pads are meticulously engineered to meet and often exceed AASHTO M251-06 Grade 5, AREMA Section 18, Caltrans Section 51, ASTM D4014, and CAN/CSA standards, making them the gold standard for heavy-duty bridge, roadway, and industrial construction applications. Our natural rubber formulation delivers outstanding elasticity and resilience—accommodating controlled expansion and contraction of precast concrete and structural steel assemblies while effectively dissipating dynamic loads, damping vibration, and reducing operational noise. This ensures long-term structural integrity and significantly extends service life, even under harsh cyclic loading and temperature fluctuations. Stocked in precise thicknesses from 1/8″ to 18″ and standard widths of 36″ and 48″, these pads also support custom molding in virtually any size, shape, or hardness (50–70 durometer) to suit project-specific requirements. Designed to perform reliably in temperatures from –40 °F to 212 °F, our natural rubber pads exhibit exceptional tear strength, abrasion resistance, and fatigue life—ideal for bridge abutments, pier caps, seismic isolators, parking garages, and heavy machinery foundations. With full compliance across all 50 states and Canada and industry-leading lead times, Hanna Rubber ensures your infrastructure projects stay on schedule and within specification.
