A Hänchen hydraulic actuator is characterized by:
  • long performance life
  • high control accuracy
  • space-saving construction
  • extremely long service intervals
  • high efficiency with very little wear and tear
  • for highly dynamic applications in the testing sector
  • custom hydraulic cylinder design for all industrial applications

Industrial hydraulic cylinders
Industrial hydraulic actuators offer a number of advantages

The essential advantage of industrial hydraulic cylinders is their ability to continuously and simultaneously provide full power at full speed - maximum working pressure, without any negative effects on the service life. All Hänchen hydraulic cylinders of 120 and 300 series also feature a characteristic compact construction.

Standard hydraulic cylinders according to DIN and ISO
Mounting dimensions according to DIN ISO 6020/6022
To guarantee exchangeability between products from different manufacturers, standard cylinder for the pressure range 160 bar can be used. Hänchen standard hydraulic cylinders comply with the required standard mounting dimensions - but their true strength is that they also meet Hänchen quality standards.

Servo hydraulic actuator
Hydraulic servo actuators with valves and sensor technology

Sensor technology such as force or position transducers allow very large operating areas. The selection of the right control strategy creates precise and highly dynamic hydraulic drives with extremely high energy densities.

Test hydraulic actuators
Servo actuators for inspection and test applications

High speeds, frequencies, accelerations: hydraulic test actuators of the 320 test cylinder series with integrated position transducers always keep up. Test actuators are used wherever high dynamics are required - in test machines or industrial applications.

Custom hydraulic cylinders
Special hydraulic cylinders - custom-tailored for you

The design and production of individual, customer-specific solutions is one of Hänchen's strong points. Thanks to decades of experience, our wide range of standardized hydraulic actuators, and the many projects we have realized, there is almost no prototype risk for our custom hydraulic cylinders.

Industrial hydraulic cylinders in Hänchen quaility

Passion for high-quality hydraulic cylinders needs a basis of accuracy down to the last detail. Our cylinder production makes no compromises on quality, giving you every reason to choose Hänchen products:


80 % Vertical Integration.

100 % Made in Germany.

100 % Quality.

Made in Germany by Hänchen

Processing
Low friction. Low wear. Long life time.

The high surface quality and geometrical accuracy of the component parts of every single Hänchen cylinder - standard or custom cylinders - guarantee a long life time without failure.

Honed surfaces

For the best lubrication and running properties and as little wear as possible on cylinders and seals, the cylinders' sliding surfaces are refined with a cross-hatch finish.

Current sealing technology

The constant development of our sealing systems - by combining already marketed and in-house developed seals - optimise all our hydraulic cylinders regarding wear, friction and leakage.

H7/f7 – Clearance fit

The guide clearance must be neither too small nor too large. This is why Hänchen places so much importance on optimal accuracy. The result is reduced stress on the guide and thus less wear on the component parts.

Design
Three components. One unit. Easy handling.

The fewer component parts a cylinder has, the less accident-prone it is. And the simpler and safer maintenance and installation is. The three main parts of a Hänchen hydraulic cylinder:

Piston rod

Our hydraulic cylinder pistons and piston rods are inseparably joined. The piston is coated with non-ferrous metal, enabling a precise metallic guide. The sophisticated rod ends with rounded edges permit a sealfriendly installation.

Cylinder tube

Round-head design, inseparably welded to the cylinder mounting. Drilled ports permit a space-saving installation with many options for adjustment to various applications.

Cover

A stick-slip-free cover type that is perfectly coordinated to the requirements is crucial for the service life of the entire hydraulic cylinder. Special feature: The synthetic guide is permanently integrated, reaches a better load distribution and minimises the risk of scratches caused by dirt particles.

Cover Equipment
Unlimited possibilities.

Perfect combination: The cover type with the best sealing and guiding system* matching piston rod quality and the right sealing material is selected based on your application.

  • high temperatures in steel mills,
  • high stress in outdoor applications,
  • hygiene requirements in food processing,
  • tests in salt spray fog, in climatic chambers or in a lab:

Low level of friction force

Whether sensitive, free-moving or robust – extreme adaptability ist the strength of each Hänchen hydraulic cylinder and servo actuator.

We offer you always the best cover type with optimal friction force for static or dynamic applications.

Table with levels of friction forces

Measured on double-rod cylinder (bore 46 mm without seal, rod Ø 40 mm) during sine operation according to VDMA 24577 at 50 °C/HLPD46.
The level of the friction force curves is lower than usual.

Piston Equipment
The perfect sealing system

Beside the selected cover type, the right piston design is also crucial for the dynamic movement of hydraulic cylinders.

Equipping the rectangular compact seal with a static elastomer seal prevents lowering of the piston rod under load holding function of the cylinder for a longer period.
