MDC’s Welded Bellows – Weldable Components deliver flexibility, durability, and ultra-high vacuum (UHV) performance in welded system assemblies. Designed as building-block components for custom vacuum configurations, these bellows are constructed from AM-350 stainless steel with 304 stainless steel end plates to ensure strength and corrosion resistance. Bellows are saw cut, deburred, and vacuum shrink-wrapped, maintaining interior surface cleanliness for immediate integration into UHV environments. MDC bellows are compatible with Conflat®, ISO, and ASA flange systems and available in custom lengths, offering precise adaptation to meet demanding system layouts.

Industry Applications

MDC’s welded vacuum bellows provide critical flexibility in ultra-high vacuum systems across semiconductor manufacturing, synchrotrons, accelerators, fusion research, and aerospace testing. Their AM-350 construction allows for repeatable flex cycles, supporting mechanical motion while maintaining leak-tight UHV integrity. These bellows facilitate thermal expansion, alignment compensation, and vibration isolation in high-temperature or motion-sensitive systems. Compatible with welded and flanged assemblies, MDC bellows are ideal for custom vacuum lines, load locks, pumping manifolds, and chambers requiring adaptable geometry without compromising vacuum performance.
