Type HESK clamping units can be mounted in a housing which is specific to the customer. Thus, the individual clamping units can be arranged according to requirements. The collets are equipped with a plane shoulder on the thread where they are tightened by means of a nut. That way they are absolutely fixed during clamping, no axial movements are possible.
