Notes	shaft length can be modified easily
Note: * 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. For an explanation of Ferrotec’s flange mounting terminology, consult Ferrotec’s Flange Mount Options page.
