Notes shaft length and flange geometry can be modified easily

* 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.
