The Winkel range of high-load combined bearing systems from Hepcomotion has an ability to withstand very high radial and axial loads: a quality that has resulted in the series’ use in a project at the World Trade Center Transportation Hub. Winkel bearings and U-profiles have been specified for the $3bn (£1.8bn) building that is being constructed on the site of the World Trade Center that was destroyed in 2001. They are essential elements in a retractable roof system in the building, which was designed by the Spanish architect Santiago Calatrava. The roof is made from glazed steel ribs that are designed to represent the wings of a bird. To allow natural sunlight to flood the building, the roof can be opened by up to 10m; this movement is guided by Winkel. According to the company, these products will create a robust and durable guide track, able to withstand the extreme loads involved. The total order comprises 224 Winkel bearings with flange plates and 445m of U-profiles. To protect the bearings from the elements, all have a special anti-corrosion coating. The company says that it secured the order through the products’ ability to tolerate enormous static and dynamic loads, their long service life and the ease with which they can be installed and replaced.
