Disc Springs

Disc Springs are conically-shaped, washer-type components designed to be axially loaded. What makes Disc Springs unique is that based on the standardized calculations of DIN 2092, the deflection for a given load is predictable and the minimum life cycle can be determined. Disc Springs can be statically loaded either continuously or intermittently, or dynamically subjected to continuous load cycling. They can be used singly or in multiples stacked parallel, in series or in a combination thereof.  More about the advantages of Disc Springs.

Here are design considerations:

Deflection and load characteristics
Loading stresses
Fatigue life
Design guidelines
Stacking
Dimensional tolerances

 The SPIROL range includes all Disc Springs specified in DIN 2093, Groups 1 and 2, Series A, B, and C.
