1.0perating characteristics of self-adjusting oscillating dampers
In a conventional oscillating damper. the damping strength (damping constant) does not change regardless of the load torque used.
Therefore, the operating speed is slower when the load torque is small, and faster when the load torque is large.
However, since the self-adjusting FYN-X2 series is designed to self-adjust the damping strength (damping constant) according to the
applied load, its motion-time fluctuates less than that of conventional dampers when the load changes.
The acceptable range of torque is 20 to 35 N•m. Please select your damper by referring to the motion-time graph below.

[Operating principles of the self-adjusting type]
As shown in the diagram to the left, the spring compressed by the movement of the cylindrical valve
alters the amount of oil flow so as to ad just the generated torque of the damper. (Patent pending)

As the level of self-adjustment may vary depending
on the range of the working angle of the actual
work, please verify under actual working
conditions before you select your damper.
