During the clamping process, the clamping sleeve reduces in length by some tenths of a mm (depending on the size of the clamping sleeve, the clamping force and the actual dimensions of the clamping sleeve and connected components), so dragging the clamped part in the direction of clamping. The resulting axial displacement of the freely clamped part (Fig. 1) can thus amount to up to 0.5 times the clamping path.
When positioned against a thrust collar or similar (Fig. 2), the axial thrust produces an intensive face contact with the clamped part.
AK and lK series clamping sleeves can be supplied in a low-thrust version. However, the retention force of these versions only achieves 0.5 times the values listed in the table.
