counterpiece.Incaseofsoftermaterials,theuseofasteelorplasticheadisrecommendedtoreducesurfacepressure.
For even greater durability at inclined impact angles, all heads are rounded in order to absorb the load with reduced
transverse force. For a secure hold, the heads are glued as well as crimped via lateral grooves for reliable positioning with
the piston rod.
Short piston rod no head(D)
Thepistonrodextendsoutofthehousingbythemaximumstrokeofthe

6 Functional description
The braking of moving masses in the end position is performed by converting kinetic energy into heat using hydraulic
damping.
6.1 Shock absorber characteristic curve
The shock absorber characteristic curve describes the development of force over the stroke of the product. This
development is the result of the design-based buildup of the internal hydraulic friction and throttle effect via the spiral
groove as well as the velocity-dependent loading of the product.
Itdependsonthefollowingparametersandcanvarywithinthespeciedranges:
• Type, viscosity and density of the oil
• Impact velocity
• Energy load due to the impact process
• Temperature
• Wear
6.1.1 Velocity-dependent behavior
Thespeciedtechnicaldataapplytotheuseofthemaximumdamperstroke.
The force that the product generates depends on the impact velocity.
• A higher velocity corresponds to a higher product force.
• The force curve over the stroke yields the energy absorption per stroke.
INFORMATION
►Duringthedesignprocess,makesurethattheenergyloadoftheapplicationisnotgreaterthanthemaximum
energy absorption per stroke.
Theproductisdesignedsothatthemaximumenergyabsorptionperstrokeispresentwithaminimumimpactvelocity.
Uptoreachingthemaximumimpactvelocity,themaximumenergyabsorptionperstrokeremainsthesameinorderto
prevent the product from being overloaded.
Belowtheminimumvelocity,theproductrespondsmoresoftlyandnolongerachievesthemaximumenergyabsorptionper
stroke.
NOTICE
Non-compliance may result in material damage.
►Makesurethatthemaximumimpactvelocityoftheproductisnotexceeded.
ÖThe resulting high forces can cause an overload, thus damaging the product.
ÖBecause the oil cannot drain quickly enough through the throttle cross-section, bouncing can occur above the
maximumimpactvelocity.
The individual degrees of hardness tend toward the following character-
isticsintheshockabsorbercharacteristiccurve:
1

Stroke [mm]
Force [N]
Hard
Medium
Soft/Supersoft
Asarule,themaximumforceincreasesfromtheminimumtomaximum
impact velocity, whereby the energy is absorbed in an earlier stroke than
themaximumstroke.
Thus the stroke that results or that is necessary for the application can
belowerthanthemaximumstrokeoftheproduct.
►Formoreinformation,refertothe"Settingthestrokeandxedstop"

6.1.2 Bypass function
The Adjustable Energy series has an internal bypass whose opening can be manually adjusted from the outside using a
knurled nut.
The adjustment of the additional throttle cross-section allows the product to be used over the entire speed range. This is
only possible for products from the Mini Energy, Standard Energy and High Energy series using preset degrees of
hardness.
Level 0
The bypass is completely closed. Closed position Open position
0% flow 100% flow
Thisallowsthemaximumenergyabsorptioninthespeedrangeofthe
Hard (H) degree of hardness.
Levels 1–4
The bypass is partially open.
For softer damping operations, as higher speeds are approached or for
lower energy absorption levels, the bypass must be opened.
Level 5
The bypass is completely open.
Using this setting, the highest speed or the lowest speed is possible.
It is not possible to assign a degree of hardness from stage 0–5.
6.2 Ambient temperature
The force of the product and thus the shock absorber characteristic curve and energy absorption depend on the viscosity
and density of the oil and thus on the ambient temperature.
• At lower ambient temperatures, the viscosity and density of the oil increase, which can result in higher forces and energy
absorption levels per stroke.
• The low ambient temperature can be counteracted due to the heating of the product as a result of damping using a
corresponding cycle time in continuous operation.
• At higher ambient temperatures, the viscosity and density of the oil decrease, which can result in lower forces and lower
maximumenergyabsorptionperstroke.
6.3 Energy absorption per hour
NOTICE
Material damage from overheating of the product
►Makesurethattheenergyabsorptionperhourdoesnotexceedthemaximumenergyabsorption.
The energy absorption per hour at which the product is placed under load results from the energy absorption per stroke
and the cycle time in continuous operation.

6.4 Operation modes
6.4.1 Continuous operation
Continuous operation represents continuous loading of the product with a certain number of cycles per unit of time.
This results in the product heating up, which yields a certain operating temperature prevailing from the thermal balance
between heat absorption due to damping and heat dissipation to the surroundings.
NOTICE
Malfunction in case of non-compliance
►When the system is at a standstill, make sure that the product does not remain in the actuated state in order to
ensurethattheproductcanberesettothestartingpositionwiththepistonrodextended.
NOTICE
Non-compliance may result in material damage.
►Ensuresu󹱺cientheatdissipationsothattheproductdoesnotheatupabovethepermittedmaximum
temperature.
6.4.2 Emergency stop operation
INFORMATION
►Please note that several products can absorb higher energy per stroke in emergency stop operation.
In emergency stop operation, the product is only used in emergencies, e.g. a failure of the machine control system.
Emergencystopoperationcancauseirregularloadingoftheproductatunpredictableintervals.
6.5 Impact angle
The impact angle results from the angular deviation between the movement of the impacting mass and the piston rod of the
product. In cases with rotational loads, the distance of the product to the instant center plays an important role. In addition,
incaseofrotationalmovements,thepositionoftheswivelingcomponenttobedampedcaninuencetheimpactanglein
the impact point and in the end position.
INFORMATION
Theproductisapprovedforamaximumimpactangle,whichlimitsthemaximumlateralforcesactinguponit.
►Pleasenotethatasideloadadaptermustbeinstalledifthemaximumpermittedimpactangleisexceeded.

10.1.3 Setting Adjustable Energy
NOTICE
Non-compliance may result in material damage.
If the product setting is too soft, the energy is not entirely absorbed.
Iftheproductsettingistoohard,bouncingandexcessiveforcesmayresult.
►Observetheprocedureforsettingtheproduct.
►Adjust the product accordingly for the energy load.
NOTICE
Material damage and malfunction in case of non-compliance
If the load of the product cannot be adapted iteratively while the system is being started up, it is necessary to
select a level for the start.
►Level5isnotrecommendedforthestart.
ÖIncomplete energy absorption can cause damage to the system.
►Pleasenotethefollowinginformationwhenstartingwithlevel0:
ÖThereisadangerthattheproductwillrespondwithexcessiveforce,whichcancausedamagetothe
product.
ÖAnoverloadofthestructureispossible.Theriskofdamagetothesystemislessforlevel0thanforlevel5.

10.1.4 Setting the stroke and xed stop
NOTICE
Non-compliance may result in material damage.
If the stroke is reduced too much, the product and mounting piece are loaded with the residual energy.
►Makesurethatthestrokeissu󹱺cientforthecompleteabsorptionoftheenergyoftheimpact.
NOTICE
Malfunction in case of non-compliance
Makesurethatahublimitof<50%relativetothemaximumstrokeismaintained.
ÖThis will avoid worsened return behavior of the piston rod.
NOTICE
Non-compliance may result in material damage.
Iftheintegratedxedstopoftheproductisusedincontinuousoperation,thiscanreducetheservicelife.
►Incontinuousoperation,useanexternalxedstop.
ÖThis reduces the product load.
Thefollowingproductvariantshaveanintegratedxedstop.Here,thebottomoftheheadmovestothexedstopofthe
product.
IntheShortpistonrodnoheadvariant,thebrakedcomponentsitsonthexedstopafterthemaximumstrokehasbeen
reached.Thistakesplaceunderconsiderationofthemaximumforcesspeciedinthecatalog.
