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.
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.
Construction size:
Ø 80 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: Zinc die-cast; Shaft: Steel
Mounting:
in any position
Rotation angle max.:
210°
Radial force P max.:
200 N
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 at the mounting
holes in such a way that the part to be braked cannot exert any
side forces on the damper. An external guide or support of the
moved part is recommended. Only a limited side load P max (see
technical data) can be exerted on the shaft. The braking effect
can take place in both directions (types FYT-H1 and FYT-LA3)
or in just one direction – top view of the shaft left-hand (L) =
anticlockwise, right-hand (R) = clockwise. With the single-sided
dampers a return damping torque occurs in the opposite direction
depending on type (see catalogue information). The rotary
dampers have a limited pivoting angle and must not be used as
an end stop. An external positive stop is to be arranged for both
limit positions.
Damping torque note:
The damping torque can be adjusted in
the area depending on type. The locking screw is to be loosened
by one or two rotations with the key provided. The damping torque
can then be adjusted with the adjustment screw. Once the desired
damping torque is set, retighten the locking screw.
Safety instructions:
Do not use rotary dampers as supports.
Provide an external guide or support.
