|Belleville Type Conical Disc Spring Washers
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.
