§Basic principle of rotary damper 
       Due to the braking action of the viscous grease on the rotating body member, the viscous grease in the body exerts a damping force on the movement of the moving member, as shown in the following figure. The magnitude of the damping force is determined by the viscosity of the viscous oil and the contact area of the oil.

§The basic principle of the rotary buffer 
      The basic structure is as shown in the figure below. When the rotating shaft rotates, the blades integrated with the shaft also rotate at the same time, and the hydraulic oil in the oil chamber will be squeezed through the blade and the body gap to the back of the blade, and the buffer outputs torque. The viscosity of the hydraulic oil, the gap between the blade and the body, and the difference in the area of the blade when the rotating shaft rotates are different.

§Temperature characteristics
        The torque generated by the damper changes when affected by ambient temperature. This is because the change in temperature causes the viscosity of the damping oil to change, and the torque output decreases with increasing temperature; it increases with the decrease of Wendi. When the temperature returns to normal, the torque will return to its original value.

§Speed characteristics
        The torque generated by the damper will be different depending on the rotational speed. In general, the rotational speed will increase and the torque will increase. The rotational speed will decrease and the torque will decrease. The torque at start-up is different from the standard torque.
