Can a train station sway in the wind?

The answer is definitely “Yes”, at least for the gigantic roof architecture that must withstand all kinds of weather. Large spherical plain bearings provide the required length compensation in the steel design. In the Lehrter train station in Berlin, for instance, numerous spherical plain bearings and bolt systems made by ELGES have been installed in the trussed frames. They support the entire Glass roof. A similar roof design, which includes ELGES bearings, covers the new connecting train station at the Cologne/Bonn airport. It is not just train stations, though, that “sway” using our traditional brand. From the dvg building in Hanover, Germany to the Hong Kong Bank in Shanghai, our zero-maintenance bearings are used all over the world. The benefits are obvious … After all, relubricating the bearing positions would be a task only acrobats could perform. In many applications, the inner ring bores of the bearings are coated with Elgoglide®. In this way, both angular

motions and weather-related axial length changes can be compensated easily over a range of several millimeters. Even moisture, usually the main enemy of bearing supports, does not stand a chance. The fabric coating is connected to the steel support body and is resistant to moisture.
