Aneroid Bellows Assemblies

Custom Aneroid Assemblies

Aneroid bellows assemblies are designed to convert changes in pressure into linear displacement. A bellows is a thin-walled convoluted tube that is leak-tight and can compress or extend axially along its convoluted length. When the bellows are assembled to end pieces that close off the ends, it will then respond when the pressure outside of the assembly is different than the pressure inside. The bellows assembly will react by extending or compressing in precise response to the differential pressure.

“As analog solutions in a digital world,” aneroid bellows can replace or back up electronic and digital sensors with no electricity needed. Our bellows are more customizable and create fewer potential points of failure.

Custom Aneroid Assemblies

MW Components is a leader in bellows manufacturing, producing metal bellows using three distinct methods (Electrodepositing, Hydroforming, and Edge-Welded Technology). Each process allows for different ranges in pressure, temperature, and tolerances. To view the differences in these processes and see which process may be right for your custom bellows assembly project, review our Bellows Technology Comparison Guide.
