Bearing Pads

Load-Bearing Pads

Iracore has developed a urethane compound with a durometer and other performance specifications that is ideal for bridge load-bearing pads.

Cast polyurethane bearing pads provide bridge designers with a bearing that has excellent load-bearing capabilities with superior physical properties, including tensile strength and tear resistance.

Case For Urethane Vs. Rubber

Urethane bridge bearings are increasingly used in bridge construction to replace older technology elastomers, such as neoprene and natural rubber.

Urethane bearings 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.

Custom Design

Iracore can custom design bridge load-bearing pads to meet design specifications.

  • Holes to clear bolts
  • Widths and lengths to meet bridge design specs

Benefits

  • 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
  • Threadolets
