Beschreibung
Zusammenfassung:	A bearing, a gas turbine unit having such a bearing, and a method for operating and for increasing the efficiency a gas turbine unit, wherein the bearing has an annular bearing body, on the axially opposing end faces of which are provided two thrust bearings, each having a plurality of bearing elements which are distributed over the circumference, project and are movable in the axial direction, and have a bearing surface. The bearing elements of each thrust bearing are hydraulically displaceable axially outwards in two stages by predetermined amounts of movement.
