Introduction
Outstanding Features
High load with limited travel (small deflection)
High load to compress small design space so better space utilization compare to other springs. Longer service or fatigue life. Please click here to see graphical representation
Ability to function as a individual element or more often in group, in different group combination, so that stack or assembly of these Disc Spring operate axially. Please click here to see graphical representation
Greater security of operation service, as failure of one Disc Spring element within a stack does not totally lead of failure of entire assembly.
Low maintenance cost as any of the failed Disc Spring in assembly could be easily replaced.
Spring load achieved by reciprocally alternating disc.
Axial load achieved by application of guide bolt or sleeve.
High damping capacity through friction, which can be increased by parallel stacking.
High endurance and fatigue strength.
Load, stack height and travel can be determined and changed as needed.
Exact determination of Disc Spring characteristic.
Reduced thickness for Disc Springs with bearing flats.

In order to achieve a load p at f = 0.75 height with disc spring having bearing flats the thickness is reduced to t' by the manufacturer. The reduction is approximately 94% of the nominal thickness. The table shown below is particularly significant for parallel stacking of Disc Spring with reduced thickness t' and must be taken into consideration.

t mm 6 8 10 12 14
t' mm 5.60 7.50 9.40 11.25 13.10
According to DIN 2093 Disc Springs with material thickness of 6 to 14 mm.
may be reduced as shown in above table.
