• Load/deflection curves of straight, progressive or regressive character according to the design requirements.
• Simple adjustment of the spring stack length by the addition or removal of individual discs, thus altering the spring stack characteristic.
• Efficient use of space and high spring forces with small deflections.
• Largely self-damping, particularly with parallel stacking.
• No setting or fatigue under normal loads.
• Long service life.
• The large range of possible applications for individual spring sizes simplifies stock-keeping.
• Single Disc with Normal Load Application.

With the load introduced at points I and III (see figure below), the pressure is calculated according to Almen & Laszlo.
