Drawing:
Remark: the first diagram shown torque vs angular speed(at room temperature:23ºC)
Oil damper torque changing by rotate speed as shown in the left drawing. Torque increase by rotate speed increasing.
The second diagram shown torque vs temperature(rotation speed:20r/min)
oil damper torque changing by temperature,generally Torque is increasing when temperature reduction and decreasing when temperature increment.

Besides, rotary damper used in home appliance, machines and any place need safe and silent open and close.
If you don't know how to use the damper, please ask us, we have professional engineer can help you to choose and guide you how to use it.
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.
Lead time is 2-4 weeks.
6. Certicate and quality
