Well. I'm wrong again. I finnished up the clutch job on my Pickup today and guess what; it had a throwout guide too. 
I just didn't notice where it ended and input shaft began due to the amount of filth packed on there from 30 years of driving. The throwout bearing doesn't ride directly on the input shaft. I'm an idiot.

Outer race of the throwout - in red in my picture.
Driven by the pressure plate spring - you're pressing the pedal, the fork pulls the PP spring back, to make room between FW and PP for the disk to spin at different speeds, IOW to disconnect the trans from the engine.
The inner race - blue - doesn't spin at all.
Because of the clutch fork / cams on the throwout.
P.S. You're not color blind, are you?
No offence.

But the main point is that when the car is in gear and the clutch disengaged, one bearing race is held stationary by the release fork and the other is spun at engine speed by the pressure plate fingers. And the transmission input shaft is not rotating since the car is in gear and not moving. On any car with a traditional manual transmission, sleeve or no sleeve.

Other than the S2000, the only clutches I've replaced were a '94 Integra and various air-cooled Volkswagens (yes, I'm old) and I don't remember a sleeve on anything other than the S2000. But memory is the second thing to go... ;-)

Yes.
Was that comment challenged in any way?
(other than the inner/outer swap?)

No sir, it was not challenged.
While there may be a difference between which race is held by the clutch release fork between "push" and "pull" clutches, the fact remains that the release bearing must slide along the input shaft, whether it touches it (lightly) or not.
I've been the dense one in this conversation. As I said earlier, we all wear that hat sometimes. And I'm quite willing to admit that I've been slow on the uptake here.

It sounds pretty bad.
It may sound worse too.
I guess like all worn roller bearings: rumble & grumble.
And you would feel it in the pedal.
what does a bad throwout bearing sound like?

would a bad throwout bearing cause a rough spot in clutch pedal travel?
