An example project BEAR engineers worked on is the Milwaukee baseball stadium retractable roof mechanical components. The roof opens via 5 pie shaped sections that pivot about large spherical bearings behind home plate, each bearing supporting over 1 million pounds. The inside of the stadium with the roof in the closed position is shown to the left. The bearing on the left supports the stadium roof behind home plate. Before installation the internal bearing rollers are visible as shown in the photograph below right.
