Edge Welded Metal Bellow Products
BellowsTech metal bellows provide the most flexibility in the smallest amount of space of any bellows technology on the market
Our welded metal bellows are engineered to allow for maximum flexibility in axial, angular and parallel offset motion. They provide a hermetic, all metal pressure barrier and seal that flexes in one or more directions.
Our bellows feature:
- Wide variety of different stock materials including 300 series Stainless Steel, Titanium, Inconel, AM 350 plus more
- Lifetime resistance to corrosive or harsh environments
- High temperature endurance
- Excellent media compatibility
- Ultra rugged construction for maximum durability
- Up to 90% stroke length
- Standard or custom one piece designs
- End pieces optional
To achieve optimum movement in vacuum and positive pressure environments we manufacture our bellows to the precise requirements specified by our customers in the Oil and Gas, Semiconductor and UHV industries where mechanical movement is the most frequent requirement.
