Okuma LB-12 Spindle Rebuild
Hello good neighbors - I have an LB-12 from the late eighties with what I think are the original spindle bearings. They are starting to growl so I'd like to replace them asap. Does anybody have any information on rebuilding the spindle (did Oluma make a manual for this?). I'm looking for information on consumable parts, tolerances, bearing nut torques, etc.
I was able to get the modern bearing numbers from NTN.
I appreciate that this is a precision repair requiring special tools and techniques, and that there will likely be several comments to the effect that I shouldn't even touch the spindle, but I'm a small one-man shop that doesn't have the funds to send the spindle out for professional repair so I'll be performing this myself.
Any help that anyone could provide would be greatly appreciated. Thank you.

Hello - sorry for bumping this old thread.
I got a LC 30 that whines from the spindel and having a hard time making a good surface like my LB 15 with same feeds and speed.
Will this be the same procedure for replacing spindel bearings?

Hello,
I have LB15 from 90' and now its time to change spinde bearings. Originally its NTN bearings but I was asking NTN suplier and they couldn't help me in this case. So my question is, where do you guys order bearings fro your okuma spindle?
PS I contacted Okuma dealer, but he was not interested in such an old machine.. Sorry for my language too
