Hello everyoneWell, I was typing in a much longer question, but to keep things short:
Would something such as the product at the link below be suitable for use in a TD125 (MkI with the captive-ball thingy) bearing? In particular one that's been rebuilt rather well -fortunately- and has essentially zero play (so I can't use too thick an oil in it 'cause the platter just won't go down.)

So far it doesn't seem to be helping speed stability much (the strobe's rather jumpy) but the sound is quite OK -- clean and fairly punchy.
Do you guys think it might work in the long run, or could it have any undesirable long-term side effects?
I'd truly appreciate any and all help.
Follow Ups:
Never use any form of film forming or solids containing lubricant in a sintered bearing. For a sintered bearing to do its thing the lubricant must be able to "pump" into and out of the pores in the bearing. The film and/or the solids will blind the pores so this won't happen.Use a relatively thin oil and allow the bearing to run in, then change to a thicker oil.

This oil does not leave any film. It is intended for trumpet valves. Valves require a lubrication that is not at all sticky. I highly doubt that this oil could do any damage to your turntable. I have used it with my trumpets and it lubricates very well. There will be almost no friction on your table or bearing with this. I have also used it on inline speed skate bearings. Not cheapy bearings but expensive swiss bearings with good results. One or two drops down the shaft and a a few drops on the subplatter shaft should do nicely. I can't be certain it will be trouble free but this is probably the least sticky lube money can buy.
Thanks both of you for your help. I just cleaned the bearing as best as I was able to (I used naphtha) and then put some clean Singer oil in it. I noticed a few things, amongst them that the spindle is ever-so-slightly bent :(.In any case, I've got a question about this whole 'sintered bearing' business: I started with a small amount of oil, but kept adding and eventually got to the point where I was doing the 'overfill and let the excess oil overflow' thing.
What I found rather strange was that there wasn't much overflow--it was more as if the oil was getting absorbed! I filled it about halfway, put the platter on, and when I took the platter off again there was like half the oil I had put in. This actually happened more than once, and there wasn't a leak anywhere that I could notice.
Were the sintered parts actually sopping up the oil? That's pretty wild.
