This damper has high torque, a thin space saving shape, and a metal appearance. This small damper is available in 2 types of torque, one that works in both directions and the other in one direction.

· Velocity characteristics.
· The torque of the disc damper changes according to the rotation speed.
· As per the figure below, generally, the torque increases as the rotation speed increases, and decreases as the rotation speed decreases.
· Regarding the torque value of the catalog, 20rpm is the torque value at the time of rotation.
· When using the rotational fall of the cover, the rotation speed is slow at the initial stage of dropping and only torque less than the rated torque value is generated.
· Temperature characteristics.
· The damper torque value (catalog rated torque value) varies according to the operating environment temperature.
· The torque decreases as the temperature rises, and rises as the temperature decreases.
· This is because the viscosity of the oil inside the damper is affected by the temperature change, hence when the temperature returns to normal, the torque also returns to its original value.
· Temperature characteristics graph is as shown in the figure
