The compressibility of bellows is largely a function of wall thickness, diameter, and geometry. We are able to customize bellows compressibility to meet very specific needs and applications.


This is important for customers who need their bellows to conform and perform despite rough conditions.


Stiffness dictates how difficult it is to change the shape of the bellows. A stiff bellows is harder to compress but generates a range of spring rates.


Travel refers to how much distance there is between the fully compressed and uncompressed state during use.
