The Auf Schalke stadium in Gelsenkirchen was completed in August 2001 after a construction time lasting almost three years, and is one of the most modern soccer stadiums in the world. In the period between games, the turf is rolled out of the stadium on guideways by means of a hydraulic system in a three-and-a-half to four-hour operation to allow regeneration and to prevent damage during other events. The south stand was specially built like a bridge for this purpose and can float freely above the opening for the playing field. The spherical plan bearings in the supports under the stand, when raised, permit the playing field to be rolled into and out of the stadium.
Maintenance-free INA rod ends are also used in the stadium in the adjustment devices for the movable stands.
