How to Use the Damper
1. The FYN-C 1 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.
Figure A
Stronger damper torqu e
allows the lid to close
gently u ntil it is fully
closed.
Figure B
Stronger damp er torqu e
prevents the lid from being fully
closed.
* Rotating shaft material Zinc die-cast (ZDC)
* Oil type

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 : 2kg
Lid dimension L : 0.4m
Gravity Center Position G: Assumed as
½ ...:--------'------"'-'
Load torque: T=2X9.8X0.4+2
=3.92N·m
Based on the above calc ulation. select FYN-C1-*403.
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.
