The shaded area (kN/mm) in the figure is the absorbed energy from between when the spring is mounted up to the maximum.

The setting stress is usually set between 1,000 N/mm² to 1,200 N/mm².

A compact shock absorber is achieved by utilizing the characteristics from the point where the spring characteristic becomes a straight line to the point where the horizontal spacing between adjacent plates becomes 0 (Pb).
We achieve this characteristic with high precision thanks to the superb technique of our craftsmen.
