Standard Disc Springs

Disc springs are shallow conical rings that can be subjected to axial loads (s. Fig.). Normally the ring thickness is constant. The load is evenly distributed over the upper inside and lower outside edge. 

Disc springs are generally manufactured from spring steel and can be subjected to static loads, rarely alternating, and to dynamic loads. Disc springs satisfy the most stringent requirements against setting loss and for fatigue strength.

Disc springs are distinguished from other spring types by the following characteristics:

• high load capacity with a small spring deflection
• considerably better space utilisation when compared with other types of springs
• high fatigue life and low creep tendency with the correct dimensioning
• different assemblies can be designed to achieve the desired load characteristics
• special materials and various surface coatings can be used
• cost-effectiveas a result of standardised sizes.
