How to use the damper1. Dampers may generate torque in both directions, clockwise, orcounter-clockwise.
2. Please make sure that a shaft attached to a damper has a bearing, as the damper itself is not fitted with one.
3. please refer to the recommended dimensions below when creating a shaft for TRD-57A. Not using the recommended shaft dimensions may cause the shaft to slip out.
| Shaft's external dimensions | ø10 0-0.03 |
| Surface hardness | HRC55 or higher |
| Quenching depth | 0.5mm or higher |
| Surface roughness | 1.0Z or lower |
| Chamfer end (Damper insertion side |
4. To insert a shaft into TRD-57A, insert the shaft while spinning it in the idling direction of the one-way clutch. (Do not force the shaft in from the regular direction. This may damage the oneway clutch.)
5. When using TRD-57A, please ensure that a shaft with specified angular dimensions is inserted in the damper's shaft opening. A wobbling shaft and damper shaft may not allow the lid to slow down properly when closing. Please see the diagrams to the right for the recommended shaft dimensions for a damper.
Damper Characteristics
1. Speed characteristics
A disk damper's torque varies according to the rotation speed. In general, as shown in the graph to the right, the torque increases as the rotation speed increases, and the torque decreases as the rotation speed decreases. Torque at 20rpm is shown in this catalogue. In a
closing lid, the rotation speed is slow when the lid begins to close, resulting in the generation of torque that is smaller than the rated torque.
2. Temperature characteristics
Damper torque (rated torque in this catalogue) varies according to the ambient temperature. As the temperature increases, the torque decreases, and as the temperature decreases, the torque increases. This is because the viscosity of the silicone oil inside the damper varies according to the temperature. The graph to the right illustrates the temperature characteristics.

1 Where does rotary damper use?
rotary dampers are applied to a wide range of products, such as cabinets, vehicles, toilet seats, bins, coffeemachines,gas stations,lawnmowers and any device with a lid or hinge that needs to open and close frequently, quietly, and smoothly.
There are also many applications in the automotive sector: handles, fuel doors, glasses holders, cup holders and many others.
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
Our company have ISO9001, 14001,TS16949 certificate. All product comply with CE and ROHS.
We have tens of patent on the dampers.
