A bearing structure has a frame, a vacuum roller mounted on the frame, operable to be axially subjected to suction air from both sides, a first bearing arranged in a first bearing housing and a second bearing arranged in a second bearing housing, and a first bearing journal disposed on a first end of the roller, and a second bearing journal disposed on a second end of the roller. The roller is mounted in the first bearing so that there is a substantially constant clearance between a first front face of the roller. The roller is mounted in the second bearing so that there is a substantially constant separation between a second front face of the roller. The second bearing housing is arranged such that the second bearing housing is axially displaceable relative to the frame.
