General instructions
This manual is for the disruption-free use of the product
types listed on page 1; its compliance is a prerequisite
for the fulfilment of any warranty claims.
Therefore, make sure to read this manual before use.
Please always maintain the specified limits from the per-
formance table (technical data). Take into account the
predominant environmental conditions and restrictions.
Note the regulations of the trade association, TÜV or
corresponding national, international and European reg-
ulations. Installation and commissioning only according
to mounting instructions.
Intended use
ACE profile dampers are an alternative product to the hydraulic
end position damper. They are used wherever moving masses
do not have to be accurately stopped and the energy does not
have to be completely absorbed. The reversible profile dampers
are intended for emergency stop and continuous uses. The
TUBUS profile dampers of the TR-L range are designed for force
absorption in an radial direction.
WARNING
If TUBUS profile dampers are used where a failure of the
product could lead to personal injuries and/or material
damage, additional safety elements must be implemented.
Free-moving masses can lead to injuries by crushing
during installation of the profile damper. Secure moving
masses against inadvertent starting with suitable safety
precautions before installing the profile damper.
Safety information
Description and function
The TR-L profile dampers of the ACE TUBUS series are
maintenance-free, ready-to-install damping elements made
from a co-polyester elastomer. The radial loading enables very
long and soft braking with a progressive energy absorption at
the end of stroke. The tube dampers were developed especially
for applications with low end forces. The energy absorption is
between 26 % and 41 %.
A structural change in the production process of these damping
elements creates a defined preloading, whereby the TUBUS
converts the occurring force into heat through friction.
One part of the occurring energy is therefore absorbed, whilst the
other part is released again by the return of the body to its original
position.
Calculation and design
In order to ensure an optimum, fault-free and durable function of
the TUBUS Profile Dampers they must be correctly dimensioned
and designed. The following parameters must be known and used
in the calculation:
- Moving mass [kg]
- Impact velocity of the mass into the profile damper(s) [m/s]
- Additionally acting propelling force, propelling power or propel-
ling torque [N, kW, Nm]
- Number of profile dampers acting in parallel [n]
- Number of strokes or cycles per hour [1/h]
The dampers must be dimensioned in such a way that the
maximum energy capacity per stroke is not exceeded during
continuous duty or for emergency stop applications. The specified
performance data and dimensions for the profile damper type
used can be found in the performance table. The correct size
of the profile dampers for emergency stop applications can be
determined with the ACE online calculation programme at www.
ace-ace.com. The calculations are based on dynamic loads.
Where necessary we will also happily send you the respective
dynamic and static characteristic curves. You can also send us

Delivery and storage
The profile damper can become damaged when opening the
packaging. Do not use cutting tools if possible.
- After delivery please check the profile dampers for any damage.
- Profile dampers can generally be stored in any position.
Maintenance and care
Profile dampers are made from one part and therefore do not need
any special maintenance. Profile dampers that are not regularly
operated (e.g. emergency stop devices) are checked at least
once per year as part of the normal safety check of the plant. The
surface is to be checked for cracks and deformations and the
mounting elements checked that they are properly secured. For
profile dampers that are regularly operated, these checks should
take place at intervals of no more than three months.
What should be noted after a damper impact?
Profile dampers that are not regularly operated are to be checked
after a damper impact.
Disassembly and disposal
The profile damper is 100 % recyclable and can be discarded in
household waste.
