<p>The disk (10) has an aperture via which the disk is connected with a rotatable shaft (2) to outwardly centrifuge leakage fluids present on a surface in a normal rotating operation. A geometry of the disk is designed such that a contour is introduced in the surface of the disk, where the contour increases a space between the disk and a motor-side ball bearing (6). The contour is implemented as a circumferential section (12) in the surface of the disk or as a circumferential undercut with a given boundary in the surface of the disk.</p> |
