Electroformed Metal Bellows
Servometer® employs a unique, patented electrodeposition process to manufacture its bellows, couplings, contacts and assemblies. This process allows careful control of the bellows wall thickness. Because the bellows walls can be made thinner than the other types (down to 0.0003 inch), they are extremely sensitive and well suited for precision instrument applications. Servometer electroformed metal bellows are extremely flexible and repeatable, lightweight, seamless and non-porous, and leak tight to 1 x 10-9 std/sec, and can provide large deflections with only very minute forces as small as 4 grams.
Many of todays sophisticated applications require miniature bellows. Servometer miniature bellows can be made as small as 0.020 inch in diameter, smaller than any other type of bellows, yet still retain full sensitivity and flexibility. Our agile manufacturing process produces bellows with...
Many of todays sophisticated applications require miniature bellows. Servometer miniature bellows can be made as small as 0.020 inch in diameter, smaller than any other type of bellows, yet still retain full sensitivity and flexibility. Our agile manufacturing process produces bellows with minimal tooling, allowing even low quantities at reasonable prices. Other companies have tried to replicate Servometers chemistry, but remain unsuccessful in creating an accurate, repeatable bellows with high cycle life and leak-tight construction.
Electrodeposited nickel bellows offer superb performance in applications such as hermetic sealing of switches, pneumatic actuators, bourdon tube replacement, aneroids, altimeters, mechanical seals, pumps, and more.
Servometers experienced engineering and manufacturing staff can design and assemble finished components to simplify installation and increase performance.

Designing with Metal Bellows Couplings
DESIGN ENGINEERS with precision rotary motion requirements such as instrumentation and fractional horsepower applications often choose electrodeposited nickel bellows because of their high performance characteristics like positive displacement , zero windup and low or minimal backlash. Servometer’s compact bellows couplings accommodate more than 30 times the angular misalignment and 15 times the compression or extension tolerated by other types of couplings.
Electroforming is the process of depositing thin layers of metal onto a mandrel through electroplating, dissolving the mandrel chemically, and leaving the plating as the final electroformed product. This white paper illustrates how electroformed components are manufactured and how they can be applied to a variety of applications.
