W*= Load in pounds
Tare Torque: The initial torque needed to overcome seal and normal assembly drag. This value must be added to starting torque
or operating torque values.
Starting Torque: Torque value required to start moving a given load (dissipates to operating torque value once the load begins
moving).
Operating Torque: Torque required to continuously raise a given load at the input RPM listed.
Translating Tube Torque: Torque required to resist the tube rotation.
