Two variations and their advantages
Pull-back with an end-stop in axial position
Draw back against the end-stop, stabilizing the clamping, Extremely rigid, Optimal holding power, Excellent concentricity after changing the clamping bush, Simple construction thus better power conversion, Short clamping length possible and Minimum clamping diameter is 20 mm.
Deadlength with a fixed clamping bushing
Radial clamping without axial movement, Optimal clamping length for blind bores, Minimum clamping diameter of 20 mm and Clamping is achieved by pulling or pushing, depending on the model.
