|3
The testing sector is a multi-faceted and sophisticated field. High speeds, frequencies, accelerations - good to know that Hänchen cylinders of the 320, 300 and 120 series always keep up. There are many factors to be considered when selecting the right cylinder. We have made this easy for our customers. Because Hänchen's complete service ranges from personal consulting to the interactive product configurator HÄKO. From the planning phase to the start-up. From individual cylinders and clamping devices to entire drive systems including documentation. From standard applications to custom-made special solutions. Decades of experience will help us find the perfect solution for you.

Bores with millimetre accuracy
The working areas can be designed individually for the respective requirements. This saves acquisition and operating costs for the required periphery and increases the energy efficiency, e.g. with regard to the system's energy input and cooling power.
+
Modular system for efficient change of applications
Switching between different test setups simply, quickly and cost-efficiently: Mounting parts und accessories such as spherical rod eyes, integrated position transducers, force transducers, mounting plates, accumulators or control valves fit cylinders with different forces, eliminating extra purchases – optimal utilization of the existing test environment.
