Bridges must operate properly even without maintenance, regardless of whether they are swing bridges, bascule bridges, drawbridges, vertical lift bridges, suspension bridges or cable-stayed bridges.
Our ELGOGLIDE® high performance plain bearings - low-friction, high load capacity dry plain bearings - are particularly suitable for these requirements. For they require no maintenance at all and are particularly suitable for accommodating swiveling motion.
They have the smallest dimensions to ISO 12240 but offer the comparably best performance. The reason: dynamic load ratings are very high in relation to the low bearing weight.
We don’t use the attribute “high performance” without proper testing. In tests, the bearings were subjected to loads of up to 600 N/mm2 under swiveling motion. This corresponds to 200% of the dynamic load rating indicated in the catalog.
Along with the most frequently used plain bearing solutions for bridges, rolling bearings can also be used in bridges, whereby spherical rolling bearings are the most typical bearing type in this case.
