How to Use the Damper
1. The uni-directional FYN-Dl is designed to generate a large torque just
before a lid closing from a vertical position, as shown in Diagram A,
comes to a full closure. When a lid is closed from a horizontal position,
as shown in Diagram B. a strong torque is generated just before the lid
is fully closed, causing the lid to not close properly. Torque is generated
in both clockwise and counterclockwise directions in the FTY-Dl series.
Unlike the FYN-Dl series. it does not have a fixed orifice for adjusting
torque. Therefore, torque remains constant at any angle.

The damper torque becomes
larger, preventing the lid from
closing completely.
The angle in which the damper torque becomes large can be customized
by modifying the inside orifice.
2. When using a damper on a lid, such as the one shown in the diagram.
use the following selection calculation to determine the damper torque.
Example)
Lid mass M : 5kg
Lid dimensions L : 0.4m
Gravity Center Position : Assumed as
½
Load torque : T = Sx9.8X0.4+ 2
=9.8N·m
Based on the above calculation,
FYN-01-*104 is selected.
3. When connecting the rotating shaft to other parts, please ensure a tight
fit between them. Without a tight fit. the lid will not slow down properly
when closing. The corresponding dimensions for fixing the rotating shaft
and the main body are as follows.
