The invention relates to an ultra-high speed spindle (1) with aerostatic and aerodynamic hybrid bearings, comprising at least two bearings (2, 3) and a rotatable shaft (4) mounted in said bearings. The first bearing (2) is biconical and consists of two half-cushions with adjacent frustoconical surfaces (10, 10') and a portion of a biconical shaft formed from two adjacent frustoconical parts (40, 50). The second bearing (3) is a radial bearing. |
