The transitions and rotating joints between the individual wagons are subjected to a variety of different forces in all directions. These include tensile and compressive forces, shocks and permanent vibrations. Robust and reliable bearing points are particularly important for such applications. iglidur plain bearings are often used here because of their high surface pressure of up to 150MPa. The tough iglidur materials withstand even high edge loads without breaking. Their variety makes it possible to find the right bearing for every application. These include materials for use at particularly high or low temperatures, for permanent movements or with high media resistance. PRT slewing ring bearings are also used in the rotating joint on the floor of light rail vehicles. The service life can be calculated for all products. To guide cables safely between two wagons, igus e-chains are used. They guide cables safely not only inside the train but also outside, despite torsion, movement and weather conditions.
