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.
