Abstract: A gasket device for a turbomachine bearing, configured to separate an oil enclosure and an air enclosure from the turbomachine, including a segmenting gasket for providing most of tightness of the device and a supporting jacket for holding the segmented gasket. The supporting jacket includes a first groove accommodating a first elastic seal for centering the supporting jacket. The supporting jacket includes a second groove accommodating a second elastic seal for centering the supporting jacket, or aligning the axis of the supporting jacket with the axis of the rotor.
