bucksaw - Got the bearing from Applied Industrial Technologies here in San Diego. They are close to where I work.

Oddly, when I went to their website to get you the link for the bearing, it showed the detail for the part number I have on my invoice, Fafnir PN202KDD5 as a "C0" (nominal clearance). See this linkand enter the PN and Fafnir and you'll see what I mean. So I went out and looked at the box that my bearing came in. The box is a "TIMKEN" and it showed the same part number 202KDD5 but there is a sticker attached to it that shows the "C1" designation. When I documented the "C1" indicator in my post, I was going by the label on the box.

Anyway, my next logical step was to look at the actual bearing on the quill itself. Here it is:

It clearly shows "202KDD5 C1 FS 50000" and the Fafnir name on it.

Anyway, if your looking to get one, call the website and talk to someone specifically OR I can see what I can do for you on my end here.

Thanks! That gives me a better way to find the exact Fafnir bearing.

I just finished an email conversation with a salesman at ebatmus.com and found out the C1 on the Timken (fafnir) 202KDD bearing and box has nothing to do with Radial Clearance. Timkin (fafnir) C1 is a code for the manufacturing site. Based on what the salesman stated, the 202KDD (P202KDD C1 FS50000) part number is a P=Loose=C3 clearance. The part number would be "T202KDD5" for the bearing to have a T(C1) Radial Clearance. I'm still not sure you can get a T(C1) clearance for this bearing. Make no mistake, Fafnir is considered one of the Top bearing brands in the world, so when you are replacing your bearings with Fafnir you are getting the best.

See post to Timkin-Fafnir break down of the bearing part number system.

Timken uses:
P=Loose=C3
R=Regular=Standard
H=Snug=C2
T=Tight

No it would be P202KDD5
P=Loose=C3

Thanks! I appreciate the feedback. Based on what you have found out, the 202KDD is a “R” or “Standard” bearing.

Correct?

I had a friend take an picture of the bearing itself and this is the part number P202KDD C1 FS50000. I would think that a company like Timken would not be identifying a Fafnir bearing as C1 radial clearance if it wasn’t.

I included MickyD's images here

The Fafnir part number is 202kdd5 but I don't think it would have a C1
clearance.Fafnir put C1 on their boxes but it didn't have anything to do with clearance.

What is the Fafnir part number for a 6202ZZ-5/8 bearing with a C1 radial clearance?

Thanks for sharing!! I certainly do not have the skills to do this kind of work, but seeing it done inspires me to keep working toward that type of craftsmanship in my woodworking at least. The education about so many things is really priceless. Two of the great things about this forum. Thanks again.:)

OMG!!! Is it possible Bill Mayo all this time has been extolling the virtues of 'his' C1 bearings when they have actually been C3???:eek:

I SURE HOPE NOT!

HIS THINKING IS CORRECT!

Bucksaw: Regarding an earlier comment(most of the slop is at the drive shaft end(para-phrased)), I do not completely understand your point. Due to the long extension of the 'back' side of the splined quill shaft, the play in the bearing WOULD be apparently greater at that end due entirely to geometry( the output end is short, the back splined end is long).
OR are you referring to the sloppiness of the spline(s) to nylon sleeve fit?? :confused:

Good research Dave. If this turns out to be true, and it probably will, you have to wonder why the heck they would choose to use a "C1" designation for a manufacturing location since it is also a bearing class designator.:confused: :confused:

The purpose of my research was a result of my inability to locate a 202KDD bearing with "C1" radial clearance. I've contacted Timken directly and am waiting for a response. When I hear back I'll update this post with the correct information. Bill's info is probably correct, he's been doing this a lot longer than I have and I have complete confidence in his advice.

I was referring to the sloppiness of the spline fit which transfers to the quill output shaft because the single bearing acts as pivot point for any play at the spline end. Two bearings would reduce the play a great deal.

Since THEY(Timken) do NOT use the Cx designation(they use T/H/R/P for C1/C2/C0/C3) THEY(Timken) apparently see NO 'problem' with using 'C1' as a plant source code.

Makes sense ONLY if your bubble only extends to the periphery of TIMKEN, INC.. Sadly such is NOT the case for US on the outside of that 'bubble'!:(

Correction 5/11/2009 The designation(timken) above for "T" should be "J". REF post 325
