Abstract
A separating disk for a disk package of a centrifuge rotor of a centrifugal separator has a tapering shape and extends around an axis of rotation and along a tapering rotary symmetric surface along the axis of rotation. There is an interspace between the separating disk and an adjacent separating disk. The separating disc has first protrusions extending outwardly from the tapering rotary symmetric surface and second protrusions extending inwardly from the tapering rotary symmetric surface. Each of the first and second protrusion are after each other in a peripheral direction and define a contact zone adapted to abut an adjacent separating disk in the disk package. The contact zones of the first protrusions are displaced in relation to the contact zones of the second protrusions seen in a normal direction with regard to the outer surface. Each contact zone has a continuously convex cross sectional shape.
