Hydraulic servo-cylinder
ø 28 - 220 mm | 326 Series HAENCHEN

The double rod cylinders of the new Hänchen series 326 are compact and smaller than their predecessors. But they are as powerful! Their new outstanding feature is the variably selectable piston diameter, which allows the piston surface area to be customised. Just tell us, for example, the force your system requires, and we shall supply you with the matching test cylinder from our modular system. The first-class seal grades Servofloat® and Servobear® (see at bottom right) are included, depending on the requirement.
The add-on parts for your first "customised cylinder" will fit for the most part also your next one. This is one of the advantages of the modular system. This is why a few manual operations is all that is needed to set up your test rig for the next job.

Other novel features include

- Swivel trunnion on cylinder tube fastening type
- Cylindrical base fastening type Higher rigidity through conical shape. Cone "keeps growing", i.e., it gets longer as the cylinder gets longer.
- Flanged head add-on part
- Force transducer add-on part - they can be screwed directly onto the piston rod wherever possible without an adapter.
