B18231 Flat clamp 

The flat clamp is a double-acting hydraulic clamping element where the piston acts via a con-rod onto a clamping lever. In unclamped position, the clamping lever is completely retracted and the workpieces can easily be inserted from above.
A clamping recess which is larger than the clamping lever is sufficient as clamping point.
The element compensates transverse forces at the clamping point.
The clamping forces are introduced vertically to the base at the clamping height „h3“, therefore introducing no additional turning moments.
