When transmitting rotary motion through some sort of environmental boundary / wall there are a variety of engineering solutions available, from simple O-ring / lip seals as might be used to contain liquids or even vacuum at the medium vacuum level, through to differentially pumped O-rings and Ferrofluidic drives for high vacuum (HV).

However, due to the much more stringent requirements in terms of leak tightness and materials outgassing properties, transmission through a wall into an Ultra High Vacuum (UHV) environment is very much more challenging.
