This superior performance is due to a special bellows design coupled with a self-lubricating bearing. This means that while the bellows assembly does not rotate, it does furnish the flexing required by the mechanism and provides the seal required for the vacuum environment. Exposed bearings on the vacuum side of the feedthrough are lubricated with a self-deposited, dry film. The feedthrough may be locked to hold the shaft in any position by means of a lock screw mounted on the drive-cap assembly. How to Order A published price list is available in our printed catalog.
