Metal-Flex® manufactures edge welded bellows from 0.200" I.D. through 14.000" O.D., with many sizes in between. If we do not have the exact bellows size you need, we can manufacture a stamping die, in house, to meet your needs.

BellowsTech is a premier manufacturer of high-quality, dependable edge-welded bellows and assemblies. The expert engineers at our BellowsTech location partner with you to produce truly optimized designs for fast prototyping or full production runs.

Welded Metal Bellows An edge-welded metal bellows is a zero leakage dynamic seal capable of a great range of motion. The metal bellows is manufactured from sheet stock.

what are edge welded metal bellows? As the name implies, Edge Welded Metal Bellows are composed of thin foil metal stampings that are welded together on the inner diameter (ID) & outer diameter (OD) edges to create a flexible hermetically sealed assembly.

Edge-welded metal bellows provide superior stroke capabilities and more precise spring rates than formed bellows, giving you greater flexibility and control in the smallest possible spaces.

As highly flexible parts, edge welded bellows are used for the absorption of movements, decoupling. lead-through, volume compensation usually in vacuum applications, or for low differential pressures.

Our Welded Bellows are the specialty offering of KSM USA (Sunnyvale, CA). By leveraging proprietary software, 3D Modeling and the expertise of both our in-process and design technical experts we have the capability to tackle the toughest engineering bottlenecks.

For high vacuum, aerospace or more stringent industrial applications, our edge welded bellows assemblies provide high over pressure capabilities and the most stroke per package size of any bellows technology. Metal bellows have long been a key component in demanding sensing and sealing applications.

MW Components’ edge welded metal bellows provide the most flexibility in the smallest amount of space of any bellows technology on the market. Edge welded metal bellows are engineered to allow for maximum flexibility in axial, angular, and parallel offset motion.

Flexaseal Engineered Seals and Systems, LLC is a world leader in engineering and manufacturing edge welded metal bellows seals and devices that can reliably operate in a wide range of applications and temperatures.
