2. When using the damper, please ensure that a shaft with
specified angular dimensions is inserted in the damper's shaft
opening. Also, please ensure a tight fit between the shaft
and the damper shaft's opening. Without a tight fit. the non
damping range becomes larger in a closing motion, etc .. and it
may not slow down properly. Please see the diagrams to the
right for the recommended shaft dimensions for a damper.
3. Damper characteristics vary according to the ambient
temperature. In general, the damper characteristics become
weaker as the temperature increases, and become stronger as
the temperature decreases. This is because the viscosity of the
oil inside the damper varies according to the temperature. When
the temperature returns to normal. the damper characteristics
will return to normal as well. The time it takes for the lid to close
is shown in the graph to the right
4. The damper's working angle is 130
°
, as shown below. Rotating
the damper beyond this angle will cause damage to the damper.
Please ensure that an external stopper is in place.

5. Because the FYN-51 series is a self-adjusting type, the torque cannot be adjusted manually. However, by altering the viscosity of the oil, its
damper characteristics can be modified. (Please contact us, as this is a custom order.)
6. The direction in which torque is generated varies according to the model Please select the appropriate model for your purpose.
