FATIGUE RATED TEST CYLINDERS


Test cylinder, servo cylinder and test cylinder with position measuring system

It’s not only in the aerospace industry that test cylinder, servo cylinder, and test cylinder with position measuring system made by Hänchen are successfully used in highly demanding applications. Test and inspection facilities are an integral part of the industrial production process. The typical applications of Hänchen test cylinders include establishing the mobile safety of vehicles, the operational reliability of machines or the functional integrity of individual products, the testing of exhaust-gas systems or the functioning of airbags, and much more.

Products under development must also be tested along with existing ones in terms of long service capability and reliability. These tests are increasingly being carried out in-house by companies—because of time and cost. The fact that this is at all possible is in no small way attributable to Hänchen test cylinders, servo cylinders, and test cylinders with position measuring system. Variable in terms of their qualitative design, and thus ideally suited for almost any application, they help make the implementation of testing systems possible for the most varied tasks.

Test result: Top!

Those who demand the very best test results will expect top quality in every detail from the test cylinder, servo cylinder, and test cylinder with position measuring system:

  • Particularly low friction
  • Optimum sealing capability
  • Excellent response characteristics
  • Low wear factor
  • Extremely high piston speed
  • Low break-away forces
  • Fatigue strength under vibratory stresses
  • Long service life
  • Efficiency

Hänchen test cylinders meet the highest technical requirements with respect to amplitude and frequency for different curve shapes.

For every case

The test cylinder models from Hänchen offer every possibility: i.e. the low-cost differential cylinder for a wide range of test purposes up to 7 Hz, with integrated or external position transducer.

For the highest demands

Synchronous cylinders for applications up to 25 Hz, 1mm stroke steps. With integrated magnetostrictive or inductive position transducer system. Maximum piston speed up to 1 m/s.

Synchronous cylinders for applications even above 25 Hz up to 800 Hz. Test forces from 4 to 400 kN. Pressure range up to 320 bar. Fixed strokes 100, 150, 200 and 250 mm. Hänchen offers various qualities, each designed for the respective requirements and for a long service life. With integrated inductive position transducer system. Maximum piston speed 6 m/s in process.
