Edge welded bellows are an essential element, which helps to keep the equipment flexible. It is used for research equipment are made mostly from material 316L. In vacuum equipment for the production of semiconductors, these are a helpful element, which encloses mechanical parts and ensure constant sealing forces. It is suitable for linear shifts, manipulators, thermal expansion compensation, cryogenic application and high temperature application. It is also used in machines such as semiconductor equipment and vibration eliminators.
