Ex. @+/- 10 seconds, on a 6" dia. piece would be +/- 0.000145" on the circumference. That may or may not be more accurate than you need. Remember, like speed, precision (accuracy) costs money. How precise (accurate) do you want to be?
There are rotary tables out there that can obtain extreme accuracy but they are extremely pricey. I just had one priced @ $28,000 for a servo driven spindle capable of 4 arc seconds accuracy and 1,000 rpm. I don't think that's what your looking for, that's just an extreme example. Sounds overly extremely redundant. lol
Tighten up a bit on the requirements and you should get a lot of info.

Again, thanks for the input. In any case that was the spec I was given. More info I got before I get all the details Monday.
Nothing said about the rpm, but the spindle torque = 190 lbs ft.
Setting position may be either, Vertical or Horizontal
(Resolution degree??) 0.0005"
Gear Ratio: 90:1
Repeatability: +/- 2 seconds
The only thing I found about about diameter is the the thru-hole which is 2.5"
