Dears,

Regarding rubber bellows, one of our known bellow vendors told that like pressure drop, the axial/lateral stiffness of rubber bellow is negligible. But, regarding torsion, he told to avoid such loading on rubber bellow. Does it mean reasonably high torsional stiffness ?

If anyone knows about these stiffness values & share, we, the CAESAR II users will learn & have a harmonized approach for rubber bellow application.
