Description
WZ 2.1330 Short-stroke hollow-piston cylinders

single acting, as pull or push cylinder

The clamping element is particularly suitable for clamping mechanical clamping bars on die bending presses and folding presses. The clamping force is built up by applying hydraulic pressure to the piston. The piston is returned by a spring which is installed in the clamping bar. The piston is provided with a through hole and is hardened and ground. For an optimum adaptation to the clamping surface, the hollow-piston cylinder can be equipped with a spherical disk.

Special versions

Customised special versions can be easily realised: 
For example,with regard to size, clamping force, clamping stroke or double acting versions.
