NOTES, ETC:

On NSK bearings: “V” = rubber seal on one side; “V V” = rubber seal on both sides; “Z” = steel shield on one side; “ZZ” = steel
shield on both sides; “DU” = heavy contact seal one side; “DDU” = heavy contact seal both sides.
“Heavy Contact” = higher drag. Normally the “V V” seal is sufficient.
I have never seen “DW” on an NSK bearing.


Ball bearing mfgrs. all use their own numbering system, although many of them are similar to each other.
Fafnir: “P” = rubber seal, “KD” = steel shield, etc.
SKF: “RS” = rubber seal, “Z” = steel shield, etc.
No suffix = no seal or shield

Seals retain grease & exclude contaminants. Shields do not – they need an auxiliary seal to do that. Often ball bearings that
are sealed or shielded on both sides are cheaper (because they are more common). You can safely pry out the seal/shield on
the side where it’s not needed. I’ve listed mostly double sealed/shielded bearings in the chart. The “C3” designation on some ball
bearings a clearance designation (the clearance, or “fit”, between the balls & the outer race). “C3” bearings are common (probably
the most common), and can be used in many applications.

Tapered roller bearing mfgrs. All use the same numbering system, although some use a “4T-” prefix.

AVOID CHINESE, TAIWANESE & EASTERN EUROPEAN BEARINGS LIKE THE PLAGUE. THEY ARE CHEAP,
BUT IN THE LONG RUN THEY ARE NOT INEXPENSIVE! GOOD BALL & ROLLER BEARINGS ARE NOT THAT
MUCH MONEY…..SPEND THE EXTRA & SAVE A LOT OF HEADACHES IN THE LONG RUN.

Some of the needle bearings in the list are obscure numbers & I left them alone

Just curious to know if anyone is using this bearing (NDH 3206) for the clutch basket anymore. It seems that they are readily available, this is what is currently installed in my clutch basket. Anybody know if this is the OEM bearing?

You're welcome, I just thought it was a little odd that it isn't listed in the bearing list here in the sticky. Do think this is the OEM bearing?

From the list here there are two other bearing numbers list for the 71 and later clutch basket. I was wondering if the one I have is maybe not as good as the ones listed in the sticky. Those two appear to be the double shielded type. I have not removed mine yet to see if it is also double shielded, definitely shielded on the exposed side.

"9007 Generator Drive End Bearing 1958-1981 FAG 6202-ZR C3 or SKF 6202Z"

I just found Napa carries this part as Napa Part # BRG 6202J for ~$16. The website lists it as Napa brand but it comes in an SKF/Napa box. This bearing contains eight balls instead of seven like some off-brands I have seen, and it comes in the open (not shielded/sealed) configuration like the original HD part.

Just want to give some credit. GA posting up these numbers has saved me lots of time trying to cross reference.

Sure with the part numbers Taiwaiin and Chinese junk is easy to find on JP or eBay but cross referencing is another animal. Thanks GA
