Abstract: A balancing device for turbochargers comprises a base body having a centrally disposed receiver. A rotation element to be balanced can be axially inserted to hold the rotation element in the receiver such as to turn about its axis of rotation. A number of hydraulic cylinders are arranged around the central receiver on the base body for fixing a core assembly of the turbocharger in the central receiver. The base body is in the form of a decoupling plate having an inner plate section and a stationarily positioned outer plate section elastically connected to the inner plate section and surrounding the inner plate section. The decoupling plate has a number of peripheral slots resiliently decoupling the inner plate section from the outer plate section such that a number of separate holding sections are formed on the de-coupling plate.
