* See the Drag Torque section of the Determining your Requirements page for the definition of starting torque

** Values are for a feedthrough at room temperature. Under continuous rotation the unit will warm-up, and the running torque will decrease.

*** Water cooling may permit significantly higher speed. Consult your Field Engineer.

General vacuum seal specifications can be found on Ferrotec’s Standard Feedthrough Common Specifications page.
