摘要
The main object of the invention is a device (10) for centering and guiding in rotation a turbomachine shaft (12), comprising: a rolling bearing comprising an outer ring (18), a bearing support (20), a hoop (28) interposed between the outer ring (18) and the bearing support (20), connecting means (29) of the outer ring (18) to the bearing support (20), characterized in that it comprises means for axial retention of the outer ring (18) comprising an axial stop flange (100) downstream and in contact with the fastening flange (30) of the connecting means, and comprising a hole of fastener (101) for fastening together the fastening flange (30), the bearing support (20) and the axial stop flange (100), which further comprises a spigot (103) extending between two successive tongues (34) of the elastically deformable means (32).
