Mounting instructions and mounting accessories
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.
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.
Construction size: Ø 47 mm to 70 mm
Max. speed: 50 rpm
Lifetime: 50,000 cycles (1 cycle = 360° left-hand,
360° right-hand), 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: -10 °C to +50 °C
Damping medium: Silicone oil
Material: Outer body: Steel; Output shaft sleeve: Nylon
Damping direction: Top view of the shaft left-hand (L) =
anticlockwise, right-hand (R) = clockwise.
Mounting: in any position
Mounting information: Secure brake at the mounting holes and
connect the part to be braked via a suitable shaft to the output
shaft sleeve. An external guide or support of the moved part is
recommended. Thanks to the flat design, numerous dampers can
be fitted in parallel to increase the damping torque.
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.
Provide an external guide or support.
On request: Special designs available on request.
