Hydraulic Expansion System SH

If there is not enough room for a mechanical clamping system, the hydraulic system SH can be used. It also allows clamping long, thin-walled workpieces or a number of similar workpieces.

System SH is a closed system filled with hydraulic oil. A force is applied on it with a piston. The hydraulic pressure radially expands the thin-walled clamping zone. The workpiece or pieces are therefore clamped.

The illustration on the left shows a cut of the clamping system in the unclamped and clamped mode.
