Disc springs are available in very large diameters up to 1000mm OD (40" O.D.). Special material, such as high nickel maraging steels for high temperatures on corrosive resistance applications, can be obtained. Our disc springs are used in special nuclear applications. Additional sophisticated disc springs have been designed and manufactured for the following:

Disc springs are precision belleville springs made of high carbon spring steel, alloy steel, stainless, and heat resisting steels and non-ferrous materials. Conical in shape and made to special geometrical relationships of OD,ID, thickness, and height, they are subject to exacting manufacturing and quality control standards. Material used are generally in annealed condition and hardened to range of RC44-51 depending on material thickness used. Load/deflection relationships are closely controlled. Disc springs are made of cold rolled strip, hot rolled sheet, or forgings of flat or conical shape. After the spring is formed by stamping, it may be machined at the inner and outer diameters or on all surfaces.
When properly designed and used, disc springs have a long life, superior performance, and may result in significant cost reduction.
Typical disc spring applications are as follows:
