Linear Feedthrough

This is a linear feedthrough to introduce linear motion into equipment installed in vacuum. It can be used in ultra-high vacuum range up to 10-8Pa.

Components

Features

  1. All-metal and capable of hard baking, suitable for ultra-high vacuum systems.
  2. This is a bellows type linear feedthrough, with the vacuum side and the air side completely separated by a bellows.
  3. Introduces linear motion into vacuum by using the expansion and contraction of the bellows, preventing the leaks during operation.
