Product Description
This product is a hardware disc damper that can rotate 360 degrees and is easy to install. Its ultra-thin appearance facilitates customer installation and is currently widely used in cinema seats and piano lids, providing cushioning and enhancing the user experience.
This product is a bidirectional damper. If unidirectional functionality is needed, a unidirectional bearing can be added to the middle shaft to achieve this, with unidirectional rotation available in clockwise and counterclockwise directions.

*Note: 1) The marked torque is measured under standard load conditions of falling at a rate of 15° per second at a temperature of 23°C and humidity of 80%.
*Note: 2) Torque customization can be provided by changing the viscosity of the damper grease.
*Note: 3) Maximum operating temperature range for the damper: -40°C to +90°C.
*Note: 4) This series of dampers includes both unidirectional and bidirectional types; among them, unidirectional dampers have both clockwise and counterclockwise directions.

4.阻尼器特性
A．温度特性：
阻尼器产生的扭矩在受到环境温度影响时会发生变化。这是由于温度的变化会使阻尼油的粘度产生变化，扭矩输出随温度的升高而降低；随温度的降低而增大。当温度恢复正常，扭矩也随之恢复到原来的数值。
B.速度特性：
阻尼器的扭矩在使用旋转速度不同时也会发生变化。一般情况下，旋转速度加快，扭矩也随之增大；旋转速度减慢，扭矩也随之减小。另启动时扭矩与标准扭矩也不同。
