How to Use the Damper
1.FYN-N2 series has been designed so that when a lid is closing
from a vertical position, as shown in Figure A, high torque is
generated just before it closes completely. For a lid that closes
from a horizontal position, as shown in Figure B, the strong torque
generated just prior to a complete closure may prevent the lid from
becoming fully closed.

2. When using a damper with a lid shown in the diagram,
determine the damper torque based on the following
selection calculation.
Example)
Lid weight M: 1.5 kg
Lid dimension L: 0.4 m
Gravity Center Position G: Assumed as
½
Load torque: T = 1.5 x 9.8 x 0.4 -;- 2
=2.94N·m
Based on the above calculation. select FYN-N2-*303.
3. When connecting parts that are joined to the rotating shaft, ensure a snug fit. The lid
will not decelerate as designed when closing if these parts are not connected properly.
The dimensional tolerance for fixing the rotating shaft and body case is shown below.
