Abstract An assembly comprises a rotating shaft (10) supported with respect to a stationary housing (16) by at least one active magnetic bearing (12) presenting a mean radial air gap (El) and at least one auxiliary bearing (18) comprising on the one hand a bushing (21) fixed to the housing (16) and on the other hand a sleeve (20) fixed on the rotating shaft (10). The bushing (21) and the sleeve (20) have opposite surfaces (24, 23) defining a clearance (E2) which is less than the mean radial air gap (El). The bushing (21) and the sleeve (20) each exhibit symmetry around a longitudinal axis of the shaft (10) whilst having different profiles in a longitudinal cross-section including the longitudinal axis to optimize the contact pressure distribution when the rotating shaft (10) lands on the auxiliary bearing. Un ensemble comprend un arbre rotatif (10) supporté par rapport à un boîtier fixe (16) par au moins un palier magnétique actif (12) présentant un espace dair radial moyen et au moins un palier auxiliaire (18) comprenant dune part, une douille (21) fixée au boîtier (16), et dautre part, un manchon (20) fixé sur larbre rotatif (10). La douille (21) et le manchon (20) ont des surfaces opposées (24, 23) définissant un dégagement inférieur à lespace dair radial moyen. La douille (21) et le manchon (20) présentent chacun une symétrie autour dun axe longitudinal de larbre (10) tout en ayant différents profils dans une section transversale longitudinale comprenant laxe longitudinal pour optimiser la répartition de la pression sur le sol lorsque larbre rotatif (10) atterrit sur le palier auxiliaire.
