Claim:
1. Balancing or measuring adapter for clamping a component on a rotating machine element of a balancing or measuring machine, the adapter comprising: a main body having a receiving opening for the component to be clamped; a collet chuck arranged axially movably inside the main body and having clamping tongues for centered clamping of the component; and an actuating element movable between a clamping position and a release position for actuating the collet chuck, wherein the clamping tongues of the collet chuck have a front clamping region associated with the component to be clamped and a rear clamping region associated with the main body, the actuating element has a first outer conical surface, which is associated with the front clamping region of the clamping tongues, and at least one second outer conical surface, which is associated with the rear clamping region of the clamping tongues, a displacement of the actuating element from the release position into the clamping position includes a first clamping phase and a second clamping phase, and the second conical surface is arranged offset axially relative to the first conical surface such that, during a displacement of the actuating element from the release position into the clamping position, the first conical surface initially engages with the clamping tongues during the first clamping phase, and later the second conical surface engages with the clamping tongues during the second clamping phase.
