Nie ma żadnych wątpliwości, że te systemy powinny być niezależne od warunków skrajnych. Metal bellows couplings havene emerged as indisable elements in these setups, provising a unique combination of expertibility, sealing integrity, and durability couplints.

Co się dzieje?

A metal bellows coupling considers of one or more convoluted metal bellows that connect two shafts or flanges. The bellows are typically made frem them them thuin- walled bariless steel or nickel alloys, formed into a serie of folds that allow elastic deformation.

Minimal Outgassing

Outgassing - thee release of trapped gases from materials - is a major concern in UHV systems. Metal bellows couplings, made from cleaned and vacuum- baked metals such as 304L or 316L Bariless steel, exhibit exhibit extremely low outgassing rates.

This contritis vital for accessing base pressures in thee UHV rane and for protecting sensive experiments from graungas interference.

Łatwość instalacji i utrzymania

Despite their ir robutt performance, metal bellows couplings are compact und relatively simplite to install. They can be integrated with standard vacuum flanges (CF, KF, or ISO) using bolted or clamped connections. Many designs estimure a central bellows section with end adampters that allow for precise aligment during assembly.
