Beschreibung
Zusammenfassung:	A bearing support journal for an internal shaft of a gas turbine engine including a device for retaining a sealing sleeve surrounding the shaft is disclosed. The retaining device includes a full radial annular flange formed upstream on an axial cylindrical part of the journal, the full flange being intended to butt axially against a radial annular flange of the sealing sleeve; and a tangential immobilizing device for immobilizing the sealing sleeve with respect to the journal, the tangential immobilizing device being created downstream on the axial cylindrical part of the journal.
