Expanding mandrel

Great power in a small installation space

Expanding mandrels can be used for different workpieces by simply exchanging the expanding sleeve. The design is possible with and without axial clamping. This design is used for long, shaft-shaped workpieces to center them on two levels and clamp them securely.
