Quality has many aspects to it
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.
Small but superior
Hänchen industrial hydraulic cylinders are compact and comprise only a few moving components, where­by the pistons are permanently fastened to the piston rods. Adjustable final stroke cushion-
ings, 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.
For high to maximum
demands: leading the way
Certain cases need more than just top quality ... they require
that something more. Hänchen
has just the right solution for such cases: extremely low-
friction hydraulic cylinders with
some very special „guiding qualities". With new piston rod
guides and various seal combin­ations: for extremely slow and extremely fast piston speeds,
with a low break-out torque, sensitive response behaviour and good reproducibility .
for the wide range of applica­tions above and beyond
standard needs, right through
to high-end solutions.
Servoslide
with plastic guide and optimised friction properties
Outstanding geometrical ttà precision of components
Servocop®
low stick-slip movements, suitable for very low and very
high piston speeds
Honed cylinder tubes (H7). Cylinder tube running surfaces with roughness of Rz A 4 pm
Servofloat
with patented annular gap seal for
exceptionally low-friction cylinder
movements
Pistons and piston rods firmly fastened to each other and processed when clamped (active piston guidance)
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
• Electromechanics
• 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.
Servobear
„High-end" solution with hydrostatic bearings, even for transverse forces on the piston rod
Sealing elements carefully tuned to surfaces and tolerances - for ideal
slider matching
Piston rods provided with
particularly thick chromium plating, with honed surfaces and a surface roughness of Rz A1 pm, piston rod tolerances (f7)
Quality in store:
The spare parts service
• At least 5000 spare parts in
stock
• Fast availability
• Spare parts list with every
spare part delivery
• Instructions on replacing seals
enclosed when delivered
• Complete documentation
