Abstract: A rotary body adapted to be subjected to centrifugal forces, with the rotary body including a load ring carried by a wheel disk or the like. The load ring is defined between two enveloping or surrounding cylindrical surfaces which respectively define the inner and outer peripheral surfaces of the load ring. The inner cylindrical surface has a diameter D.sub.i with the outer cylindrical surface having a diameter D.sub.a. At least one axially extending vacant bore is arranged in the load ring, with the bore being disposed at a position spaced from a center of rotation of the rotary body by a distance which is less than 1/4 (D.sub.i +D.sub.a).
