When one considers that a Hänchen
hydraulic cylinder works
perfectly for 40 years without breaking down, then one doesn’t
have to mention anything more about the quality of Hänchen
products. Nonetheless, as with time demands too also change
and thus it is only consistent if Hänchen repeatedly aligns its
quality considerations in response to developments in the
market.
Quality-based work
With its declared belief in a
hydraulic cylinder core proficiency
and its systematic implementation
in high-grade products,
Hänchen has laid down the milestones
for an assured corporate
future.
This also includes picking up on
the latest trends such as
• Electrohydraulics
• Hydro-mechatronics
• Design software
Typical for Hänchen:
the surface quality
One of the most striking areas
of the literal quality of Hänchen
products is the surface: all
cylinder barrels are honed (H7),
the piston rods covered with a
particularly thick chromium
plating and then rehoned (f7).
This applies in principle to all
Hänchen
hydraulic cylinders.
“Inner values“
of Hänchen products
Next to surface quality, the welded
circular construction is also essential
for trouble-free and durable
operation. It is responsible for
the outstanding geometrical
accuracy of the component. The
quality of sealing combinations,
which are perfectly matched to
surfaces and tolerances, of
electronic components and of
fastening parts is subject to
stringent testing – here Hänchen
knows no compromise. Low
break-out torque, high efficiency,
the finest reproducibility, ideal
slider matching and a top
response characteristic belong
to the so-called “inner values“,
which Hänchen passes on to its
products.

stock
• Fast availability
• Spare parts list with every
spare part delivery
• Instructions on replacing seals
enclosed when delivered
• Complete documentation
enables the precise definition
of spare parts for all Hänchen
products – for decades
• Ratings plate on every
Hänchen cylinder with commission
number (this is also
imprinted on the cylinder)
allows an absolutely identical
reproduction
Small but superior
Hänchen
hydraulic cylinders are
compact and comprise only a
few moving components, whereby
the pistons are permanently
fastened to the piston rods.
Adjustable final stroke cushionings,
simple venting capability,
permanent operation at the
specified working pressure, easy
installation of fastening parts as
well as a comprehensive range
of accessories – the Hänchen
way of responding to questions
regarding suitable solutions.
