You mean there isn't a "real" bearing so much as it is just steel running on cast iron? I'm pretty ignorant about metallurgy, and I apologize if I'm not educated enough to notice sarcasm, but am I correct in thinking that is a bad thing?

It is a "real" bearing that works quite well at the low speeds at which these lathes operate. The competition of the time (Atlas) used ball bearings to avoid precision finishing and make the lathe cheaper to manufacture. The 9" Workshop was sold for around 40 years, and may very well be the most popular lathe on the planet.
Here is Mr. Wells repository of SB data:
If designed correctly, the spindle pulls in and floats on a film of oil:

Okay, thanks, didn't know the longevity of that as a bearing surface.

That really is a keeper, will come handy with my 9". Thanks.
