A force-measuring device is provided for integrating measurement of at least three radial forces acting centrally, in particular for radial presses or collets. The force-measuring device comprises a stretching-element assembly, which is concentric to a measurement axis and which comprises at least one stretching element. The force-measuring device also has at least three pressure elements spaced from each other in a circumferential direction, wherein two spreading elements are connected to the at least one stretching element at ends of the stretching element, the pressure elements are supported, by means of pressure inclines, on corresponding sliding inclines of the spreading elements, a transmitting element is fastened to a first of the two spreading elements, and a measuring sensor acts between the second of the two spreading elements and the transmitting element.
