How to Use the Damper
1. FYN-D3 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.
Diagram A
he d amper torque becomes
larger. preventing the lid from
slowing down.

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-D3-*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.
