Abstract (en)
[origin: EP0794273A1] An open-end spinning apparatus has a rotor mounted via its shaft on support discs on which an axial force is exerted, buttressed by an aerostatic axial bearing (6) with an active surface consisting of a carbon material. The surface of the shaft (11) which works in conjunction with the axial bearing is made at least partially from a carbide. Preferably the carbide is boron or silicon carbide and is applied as an extension to the shaft or as a layer, the bearing surface being ground flat.
