Welded bellows
The cheapest, fastest, and highest quality welded bellows anywhere.
With the electroforming method, precise control of plate thickness is possible! Miniature size and flexible bellows!
The miniature bellows from Servometer are capable of achieving a very thin bellows plate thickness through an electrodeposition process, making them both "miniature-sized" and "highly flexible." They have a proven track record in applications where quality, reliability, and long lifespan are critical, such as metal sealing seals, volume compensators, pressure and temperature sensors, and flexible connectors. **Features** - Realizes high-sensitivity bellows through precise control of plate thickness via the electrodeposition process. - Ideal for applications requiring small loads for strokes and bending angles due to flexibility. - Allows for a larger inner diameter/outer diameter ratio, significantly increasing volumetric displacement capability. - No seams or permeability! Eliminates concerns about dust and debris that can cause contamination, while maintaining an extremely low leak level.
