Anybody just happen to have a set of new old stock Fafnir MM9306WI2 DUH
ACBs they'ld sell relatively cheap? I see one on Ebay, but its not
clear if its one bearing or a set.

I replaced the set on the X and its so smooth its scary. It really
drew attention to the fact that the Y is not as smooth as it should be.

I guess I can't complain. The machine is over 35 years old.

Timken replacements are pretty expensive. RHPs are a little less. If I
have to buy them I have to buy them, but that doesn't stop me from
shopping around a bit first. Most MFGs don't seem to have the size at
all. 20 x 47 x 15.88 heavy preload.

Boca has a set that says light preload, but I'm not sure that's a good
idea.

Bob...CALL these people. Ask for an engineer.

some of the best bearing prices Ive ever seen..and I buy a lot of
bearings.

They have everything from Grade 9 Swiss to 10 for a buck Chicom
bearings. Im sure they will be able to take care of you well enough.

Im in there at least 2x a month.

They were one of the first I contacted. They couldn't even cross
reference the bearing. Boca looked it up and got it wrong. Eventually
I looked up the bearing on the Timken website (came up in a Google
search but not on a site search), and verified the dimensions and load.
Locate Bearings were able to cross reference it themselves, and when
they did they got it right. It boiled down to who had what I wanted and
got the specs right the first time.

Its seems to be a bit of an odd ACB bearing these days. 20 x 47 x
15.88. Only a few companies seem to make them anymore.

There were couple new old stock Fafnir sets on Ebay the week before
last, and I bought one. I wish I had bought both sets. Oh well.
Others are listed as one bearing, used, or for near retail of new stock
Timken bearings.


For the odd bearings...try Alpine Bearing.

https://alpinebearing.com/

They are marvelous for finding bearings no one else can.



I'll keep them in mind for next time. Thanks.

I had to rebuild a Mitchell gear hobber..made in England, that used a
flat roller bearing 18" in diameter..which was toast. No markings
visible anywhere. I took it to Alpine..they did the
measurements...found the last 2 of these bearings in the world..on the
shelf somewhere in Germany...and I had one in my hands in 5 days.
Really good people.
