ABSTRACT:
A bearing arrangement with rolling elements is arranged between an outer bearing race and an inner bearing race. The inner bearing race includes a first half-race fastened to the rotating shaft and a second half-race. The bearing arrangement includes a maintaining unit which maintains the two half-races together. The maintaining unit is designed to break or deform when the bearing is subjected to a misalignment or a moment above a predetermined value, so as to allow an axial displacement of the second half-race with respect to the first half-race. The invention may be applied to a bearing for a rotating shaft of a turbine engine.
