Bearing Pads


Multi Roller Bearings


Large longitudinal movements can be accommodated by these bearings, but vertical loads only can generally be resisted.


Multiple roller bearings used in the I-35W bridge, are used to transfer loads from the deck to the superstructure as weight burdens vary or weather conditions change. Their primary purpose is to redistribute major longitudinal shifts in load. Elastomeric and fluoropolymer materials are sometimes used in bearing systems, but often for different purposes than the steel system used on the Minneapolis Interstate bridge.


It’s likely that engineers will put new emphasis on potential use of polymeric materials as a result of the calamity.
