Intended use of the washers is as follows:

a. Belleville washers are intended for use as compression springs where high loads in limited spaces are required. These washers can be used to maintain load or tension in bolted assemblies and to assure proper positioning and tension of ball bearings.

b. Curved spring washers are intended to exert relatively light thrust loads and to take up end play.

c. Wave spring washers are used in thrust loading applications where the allowable amount of axial space is limited.
