A balancing or measuring device includes a main body which is rotatable about an axis and includes an opening for accommodating a coupling shaft of a component to be balanced or measured, and having a centering element which can be axially displaced within the main body against a spring arrangement to center the component in the main body. In order to ensure maximum concentricity also in a balancing or measuring device having a small number of parts, the spring arrangement is designed to be integral with the centering element.
