How to use the damper:

1.TRD-N1 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.

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. 

How to Use the Damper
Example) Lid mass M: 1.5 kg
Lid dimensions L: 0.4m
Load torque: T=1.5X0.4X9.8÷2=2.94N·m
Based on the above calculation,TRD-N1-*303 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.
