Special features:
single-acting without spring return, as pull or push cylinder.
Installation is possible by insertion, screwing in or manifold mounting in any position. The clamping force is generated by applying hydraulic pressure to the piston, and unclamping is made mechanically by external force effect.
The piston is provided with a through hole and is hardened and ground. The housing of the hollow-piston cylinder is made of high alloy steel, the surface is black oxided.

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

Manual positioning of the element on the die clamping edge.
Unclamping by the application of hydraulic pressure to the piston and clamping by spring force. By means of the T-bolt the die is clamped against the clamping surface of the press ram or bed.

Versions
Hollow-piston cylinders with spherical disk for the adaptation to the clamping surface with adjusted and secured T-bolt (alternatively: without or with attached T-bolt)
Hollow-piston cylinders - ”L” design, without spherical disk for the adaptation to the clamping surface. T-bolt attached
Version with a total stroke of 20 mm
Optimum adaptation to varying heights of the clamping edges of dies by an increased total stroke of 20 mm (higher total stroke on request).
Technical design, clamping forces and dimensions are as indicated on data sheet 3.2130 for the standard design.
Version with variable clamping dimension
Freely adjustable and flexible adaptation to suit varying heights of clamping edges of the dies by quick and easy adjustment of the tie rod by means of a lock nut. The tie rod is inserted through the hollow-piston cylinder and adjusted to the the correct dimension by means of the lock nut.
In this version, the cylinder has a through hole instead of a thread. Technical design, clamping forces and dimensions are as shown on catalogue sheet 3.2130 for the standard design.
