What kind of oil for antique bronze bearings?

[nelstomlinson]

I just got a Myford ML2 lathe. It has bronze bearings with tiny oil cups. What's a good oil to use there?

I have some transformer oil, which I believe is just a light mineral oil. Is that the right kind of thing?

Vactra #2 or similar.

That looks like a way oil. It's good for the bearings, too?

In that application, yes...

Yes it is slideway lubricant.

Ways are just linear bearings.

Slow speed like your little lathe. It will be good.

OK, thank you both.

Now I just need to find a source for Vactra in Interior Alaska. Doesn't look like Napa has it, so I'll have to start calling Fairbanks.

hypoid gear oil API 80w90 or just 90w will also work , although it does stink a little, the anti wiping properties helps it stay on. It all depends on how much of a purist you are

I would not use a gear oil, especially a GL-5 or hypoid gear oil the sulfur
in the oil will attack the copper in the bearings.

I think my last jug was $25ish...

There are other brands besides Vactra. I've been using Fuchs lubricants for years. It really depends on what you can find locally...
