Wobble stick feedthroughs offer an economical method of providing both angular and linear movement.

 

  The position of the wobble stick must be manually held by the operator or customer provided position lock. Under vacuum load the bellows are compressed and the shaft is completely extended into the vacuum chamber, unless restrained.

 

  The two models offered are capable of 44º (0.5 inch linear) and 60º (1 inch linear) of angular motion respectively. However, when mounted on a typical necked port, the angular motion can be reduced to 20º and 30º respectively.

 

  Feedthroughs are available on Conflat® style CF metal seal or ISO-KF style elastomer seal flanges.
