The internal clamping sets can be used to fasten all types of hubs to commercially available shafts. Each type offers the following advantages: self-centring, self-locking taper angle, increased concentricity due to pre-centring.

The shrink disc is outside the flow of force when the system is in operation. Only very low dynamic loads and no wear occur on the shrink disc. The shrink disc is therefore fatigue-resistant when correctly designed.
