WARNING
If ACE rotary 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, such as lids, flaps, covers etc., can
lead to injuries by crushing during installation of the rotary
dampers. Secure moving flap/mass against falling down!
Intended use
ACE rotary dampers ensure the controlled opening and closing of
small covers, compartments and drawers. They can brake directly
at the pivot point or linearly via rack and pinion to attain a smooth
and quiet movement. Sensitive components are preserved. The
harmoniously gentle process increases the quality and value of
the product.
Description and function
On the rotary dampers with a partial rotation angle the fluid is
pressed from one chamber to another by the rotor movement. The
damping torque is determined by the viscosity of the fluid or the
dimensioning of the damping orifice or metering orifice. During
each reverse movement of the unilateral decelerating versions
there is a certain return damping torque that depends on the size.
ACE rotary dampers are maintenance-free and ready-to-install.
The damping direction can be rotating left or right. The outer
bodies are made of plastic. The dampers can be mounted directly
at the pivot point.
Safety information
Delivery and storage
- After delivery please check the rotary dampers for any damage.
- The rotary damper can become damaged if it falls. Carefully
remove rotary damper from the packaging.
- Rotary dampers can generally be stored in any position.
- Storage in the original packaging is preferred.
- Always store rotary dampers dry.
- The recommended maximum storage time is two years.
- Storage of rotary dampers is permissible at -20 °C to +70 °C.
Maintenance and care
Regularly check the rotary damper for oil loss and external dam-
age. Rotary dampers are machine elements that are subject to
continuous wear. Increased service life results in reduced braking
effect. If this is no longer sufficient, the rotary dampers must be
replaced or exchanged as appropriate.
Disassembly and disposal
Take account of environmental protection (recovery of problematic
substances) during disposal of the rotary dampers. The rotary
dampers are filled with silicone oil. The corresponding data sheet
is available on request. By design, the silicone oil cannot be
refilled. The rotary dampers cannot be repaired. Faulty brakes can
be sent to our service department for determination of the cause
of failure.
Calculation steps
1. Calculate torque for unfavourable angle
(see example on left: 0°).
2. Determine angular speed.
3. Choose a suitable rotary damper for the calculated torque.
4. With the aid of the damper performance curve, check whether
the rpm matches the desired speed.
5. If the rpm is too high – choose a higher torque.
6. If the rpm is too low – choose a lower torque.

Calculation example: Damping of a flap
In order to select a suitable rotary damper for the calculation
example shown, the length and the weight or centre of gravity of
the flap must be specified. Once the max. torque value with an
unfavourable angle of the flap has been determined, a suitable
brake is selected.
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.
Always maintain the limits specified in the performance
table. Take into account the predominant environmental
conditions and restrictions. Note the regulations of
the trade association, TÜV or corresponding national,
international and European regulations. Installation and
commissioning only according to mounting instructions.
Calculation and design
In order to ensure an optimum fault-free and durable function of the rotary dampers, they must be correctly dimensioned and designed. The following parameters
must be known and used in the calculation.
- Temperature
- Damping torque
- Speed
- Cycle number
Should you have any further questions about the use of rotary dampers, please contact one of our ACE technicians.

Installation instructions
Before installation and use check whether the identification num-
ber on the product or on the packaging matches the respective
designation on the delivery note.
Rotary dampers are maintenance-free and ready-to-in-
stall.
Construction size: Ø 18.5 mm
Lifetime: 50,000 cycles, at least 80 % of the original damping
torque after this. The service life may be significantly higher or
lower, depending on the application.
Operating temperature range: -5 °C to +50 °C
Material: Outer body, shaft: Plastic
Mounting: in any position
Rotation angle max.: 115 °
Damping medium: Silicone oil
Damping direction: Right hand damping = damping action in
clockwise direction
(when looking onto the output shaft or output shaft sleeve,
depending on the damper type). A play of approx. 5° can occur at
the beginning of movement.
Mounting information: Attach the damper in such a way that
the part to be braked cannot exert any side forces on the damper.
The FYN-P1/-N1/-U1 range is to be secured via the square mount
on the bottom. The braking effect takes place in one direction –
top view of the shaft left-hand (L) = anticlockwise, right-hand (R)
= clockwise. In the other direction a return damping torque occurs
depending on the type. The rotary dampers have a partial rotation
angle and must not be used as an end stop. An external positive
stop is to be arranged for both limit positions.
No axial or radial forces may be introduced via the shaft. The
WARNING
The specified rated damping torque
applies at a temperature of 23 °C or a
speed of 20 rpm. The damping torque can change depending
on the temperature or speed. Please observe the characteristic
curves in the mounting instructions.
The flap/mass can fall off during installation and removal
of the rotary damper. Secure moving flap/mass against falling
down!
Depending on the application, failure of the product could
lead to personal injuries and/or material damage. Use
additional safety elements.
Exceeding the permissible temperature range, the max.
speed, the cycle number and the specified damping torque
can lead to premature failure or destruction of the rotary
damper. Operating temperature range, speed of 50 rpm, cycle
number of
12/min. and the specified damping torque must be maintained.
Dirt, swarf and aggressive liquids can cause premature
failure of the rotary damper. Protect or encapsulate rotary
damper from external materials in the surrounding area.
Do not use rotary dampers in high-pressure or vacuum
range.
Note! The rotary axes, square mounts or free-wheel
mounts are not designed for side loading.
Packaging disposal: Please dispose of the transportation pack-
aging in an environmentally-friendly manner. Recycling packaging
materials saves raw materials and reduces waste. The packaging
materials do not contain any prohibited materials.

Warranty
Fundamentally, all modifications to the product by third parties
lead to exclusion from the warranty.
Obvious defects must be reported to the vendor in writing immedi-
ately after delivery, no later than one week, but in any case before
processing or installation, otherwise the assertion of a warranty
claim is excluded. A timely dispatch is sufficient to keep the term.
The vendor is to be given an opportunity to check on site. If the
complaint is justified the vendor offers warranty by repair or re-
placement at its own discretion. If the rectification fails, the buyer
may choose to demand reduction of payment or cancellation of
the contract. If there is only a minor lack of conformity, particularly
with only minor defects, the buyer nevertheless has a right of
withdrawal.
If, after failed rectification, the buyer chooses to cancel the
contract due to a defect of title or material defect, they are not
entitled to additionally claim for damages.
If, after failed fulfilment, the buyer chooses compensation, the
goods remain with the buyer, if this is reasonable. The compen-
sation is limited to the difference between the purchase price and
the value of the defective item. This does not apply if the vendor
maliciously causes the breach of contract.
The quality of the goods is only considered as agreed upon with
the product description of the vendor. Public statements, claims
or advertising of the manufacturer do not represent an additional
contractual specification of quality of the goods.
If the buyer receives defective mounting instructions, the buyer
is only obligated to deliver defect-free mounting instructions and
only if the defect to the mounting instructions prevents proper
mounting.
The warranty period is two years and begins upon completion.
Exchange and return of custom products are fundamentally
excluded. The factory conditions of the manufacturing factory
apply to parts not manufactured and processed by the vendor,
which can be viewed by the orderer at the vendor at any time.
Construction and installation parts are delivered according to the
present standard of engineering.

Manufacturer's declarationExpected service life
ACE rotary dampers are generally tested for a lifetime of 50,000
cycles with a max. speed of 50 rpm and a max. cycle number of
10/min. After this the dampers still have approx. 80 % of their
original damping torque. Depending on use the service life can
be significantly longer or shorter. In practice significantly longer
lifetimes have been achieved.
