Hydraulic cylinder as guide pillar
in founding frames

The hydraulic guide pillar is an externally hardened pillar with an integrated hydraulic cylinder. This way, loads coupled with the piston rod can be precisely guided and moved without straining the cylinder with side loads.

With the hydraulic guide pillar, two functions can be realised with one structural element while saving space at the same time: the linear movement of a hydraulic cylinder and the exact guide of a round pillar. Very high guide forces can be transmitted thanks to the hardened surface of the guide pillar.

Core pull cylinders
for die-casting moulds

Core pull cylinders are especially sturdy hydraulic cylinders adapted to the requirements in die-casting machines.

With the externally installed position detection system with limit switch, both end positions can be set flexibly to any position. The piston rod is torsion-locked by the position detection system.

A modern sealing system prolongs the service life of the cylinders.
