The invention relates to an arrangement comprising a rotational body rotatable about a longitudinal centre axis and composed of a plurality of identical adjacent elements ( 10 ). The elements are fixed relative to each other in the circumferential direction and are separated axially. For balancing of the rotational body, the elements ( 10 ) each have, on one side, an axially directed projection ( 14 ) and, on its reverse side, a notch ( 16 ), which is angularly displaced a certain amount from the projection ( 14 ) in the circumferential direction of the element. |
