Borrelly Diaphragm Washers
Diaphragm washers are a special case of Belleville disc springs.
The diaphragm washer can deliver a wide range of elasticity curves and can handle large loads. Thus, it can behave as a multi-turn spring but can also deliver the elasticity curve you need to resolve your challenge.

Technical description
The localized stresses at the base of the teeth allow, combined with proper sizing, mean that a wide variety of elasticity curves can be obtained.
This means that we can have a spring that gets stronger when it is released and not when it is compressed.

This means that we can have a spring that gets stronger when it is released and not when it is compressed.
Diaphragm washers can also deliver greater deflections (in terms of elastic deformation) without much variation in force. This feature is of particular interest when one is looking for a stable preload over a broad tolerance range.

Thus, diaphragm washer delivers elasticity curves perfectly adapted to the problem to be solved.
Our Engineering & Design Department can study any geometry of Diaphragm washers according to your specifications, for technical and precise applications in materials even under the most severe environments. Our production workshops can supply you with these washers, from prototypes to very large.
We study your needs to design your custom spring washers.
