in any position
Tooth:
Involute gearing (addendum modification coefficient:
+0.375)
P.C.D.:
12 mm
Number of teeth:
12
Module:
1
Damping medium:
Silicone oil
Damping direction:
Top view of the shaft left-hand (L) =
anticlockwise, right-hand (R) = clockwise.
Mounting information:
Attach the damper to the securing tabs
in such a way that the part to be braked cannot exert any side
forces on the damper. No axial or radial forces may be introduced
via the shaft. The rotary axis was not designed for side loading
(see diagrams).
Safety instructions:
Do not use rotary dampers as supports.
Angular offset
Misalignment
Side loading
End loading
Note! The rotary axes, square mounts or free-wheel
mounts are not designed for side loading.
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.

The indicated damping torques refer to a rotational speed of 20 rpm and an ambient temperature of 23 °C.
WARNING
The specified rated damping torque applies at a tempera-
ture 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 10/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.
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.
Provide an external guide or support.
On request:
Special designs available on request. Toothed
plastic racks (modules 0.5 to 1.0) are available for the rotary
dampers with pinions.
