No, I'm sure it is a reduction, not a speed-up. The top speed of 1043
RPM is
a strong clue.

Yes, that's right on target. 1043 RPM out x 5.9 = 6154 motor RPM.

No, motors (other than linear) do not have thrust. Without knowing the type
and TPI of the screw, thrust is a MEANINGLESS number! This should have been
your first clue that these guys are not being very clear, at the least.
The motor is
rated at 175 Oz-In of torque, but only if you can feed it 8 Amps.

So, back to, which servo amps do you have?
