Description:

Disc springs are used to maintain load or tension in bolted assemblies.

Advantages:

Belleville springs maintain high tension compensating for different expansion of dissimilar metals such as electrical connection bolting or in wear situations. This series should not be used in precision mechanical equipment or in dynamic application without detailed stress studies. Alternate materials are available for most sizes.
