Conical discs are widely used as compression springs to support large loads, when space in the direction of loading is limited. These washers may be stacked for increased loads and/or deflection. (See Hi-Stak™ Spring Pak™.)
Certain conical disc spring designs permit the washer to have “oil canning” or “snap through” characteristics. (Snap through is when a washer is stable on either side of the flat position.)True Belleville washers do not take on a permanent set on application. A permanent set, due to stresses exceeding the elastic limit of the washer material, can result in internal strains and washer failures. Conical Disc Spring Washers will take on a permanent set when over stressed.Uses include:
