Bellows Data Standard Flange Data Download Bellows Catalog (.pdf)

Notes:

Life expectancy should be 10,000 full stroke cycles(min), when operated with vacuum internal and atmospheric pressure external.
Spring rate is the force (lbs./in.) required to move the bellows one inch in an axial motion. This figure is directly related to the number of segments in the bellows. Example: a bellows consisting of two segments will have a spring rate of half the value listed.
Due to commercial mill tolerances for thin strip material, the bellows spring rate and/or free length may vary by 10% between manufacturing lots.
Mean effective area is figured as (o.d. + i.d.)² x .1963.

Data shown applies to one segment (10 convolutions).
