Edge welded bellows

UHV Design supply a range of high quality edge welded bellows fully compatible with UHV environments. Applications vary from precise research experiments, to semiconductor, data storage fabrication and industrial products. The range contains three different series: -

bullet

standard series suitable for most applications (click here to view)

bullet

wide bore series for large strokes and small forces

bullet

small series for mechanical seals and custom designs

To ensure system compatibility, each series can be manufactured in various materials including stainless steel 316L and AM 350, along with Titanium, Inconel, and Hastelloy. These materials provide the capacity to deal with corrosive environments, particularly high or low temperatures and to minimise magnetic permeability (click here to view material data).

Standard bellows have a design life of 10,000 cycles, though customised assemblies can be supplied with a design life in excess of 1 million cycles. Customised bellows are available upon request.  Click here to view the standard bellows terminations offered.   Following is a summary of the various bellows available.
