The clamping device, consisting of a combination of a HYDRA Expansion Chuck and a HYDRA Expansion Arbor, is mounted directly onto the balancing machine spindle via a bolted connection.

The workpiece is clamped by tightening a radially oriented clamping screw. During this process, the component is precisely centered and securely clamped across two clamping areas. In addition, the workpiece is securely clamped by an axial cap and a tightening screw.

Throughout the entire balancing process, no additional forces are transferred to the spindle bearings. As a result, the bearing system remains unloaded and the measurement results are not influenced by external factors.
