Hydraulic cylinder as guide pillar
in casting racks

The hydraulic guide pillar is an externally hardened pillar with an integrated hydraulic cylinder. This allows loads coupled to the piston rod to be precisely guided and moved without subjecting the cylinder itself to side loads.

With the hydraulic guide pillar, two functions can be achieved with one component in a space-saving manner: the linear movement of a hydraulic cylinder and the exact guide of a round pillar. Due to the hardened surface of the guide pillar, very large guide forces can be transmitted.

Core pull cylinders
for die casting molds

Core pull cylinders are particularly robust hydraulic cylinders that are adapted to the requirements in die casting machines.

Thanks to the externally mounted position detection system with limit switch, both end positions can be flexibly positioned to any position. The piston rod is secured against rotation by the position detection system.

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