The stainless steel locking assembly SZ (clamping set) has various advantages. It is self-centering. Machining of the shaft is not necessary (no keyway, no cross bore, no thread etc. are necessary). It impresses with its high concentricity, because there is no play between shaft and bore. The locking assembly has good vibration characteristics because the locking assembly is practically balanced. It requires little installation space, i.e. it is very space-saving and can be reused.
