Bridge Bearing Pads
Iracore has developed a urethane compound with a durometer and other performance specifications that is ideal for bridge bearing pads.
Cast polyurethane load-bearing pads provide bridge designers with a product that has excellent load-bearing capabilities with superior physical properties, including tensile strength and tear resistance.
Urethane vs. Rubber Bridge Bearing Pads
Urethane bridge bearings are increasingly used in bridge construction to replace older technology elastomers, such as neoprene and natural rubber.
Urethane load-bearing pads outperform rubber in terms of abrasion resistance and resistance to ground-level ozone. Over time, rubber gradually cracks and deteriorates due to exposure to ground-level ozone produced by automobiles and electrical discharges.
Iracore can custom design bridge and other load-bearing pads to meet design specifications.
- Holes to clear bolts
- Widths and lengths to meet bridge design specs
Benefits of Our Urethane Bridge Bearing Pads
- Retain performance and durability at temperatures as low as -40 degrees F
- Manufactured with Iracore’s proprietary urethane, allowing them to resist abrasion and impact better than other elastomers/rubber
- Highly resistant to sliding impact abrasion and bearing loads
- Engineered to outperform and outlast conventional polyurethanes, polyethylenes, rubber, neoprene and steel
- Cost effective and, in most cases, competitively priced with conventional rubber and neoprene pads
- Meets BNSF specification
- AREMA railway engineering specification
- Expansion barrels
