Well fellas, seems that the company that I said has the bearing, does in fact have the bearing!



Glad I could find a source for you all!

What's the final cost on it shipped?

[Rettic]

Knew i forgot something, ended up being 51.40 shipped. (Seems 18 shipping) They never sent me an actual invoice including the shipping price. Invoice said 34 for the part.

So that comes out right about what it was costing us through the other sources we were getting them through. I wonder how reliable their source is, and how many they are going to be able to get? In other words, did Yamaha release the exclusive on them so that any bearing house can now get them so they could become generally available if the demand was there? (I know it's not, but maybe enough demand to at least keep them available on special order).

I think I may have found a source online. Not sure the quantity they have but I ordered one. Will let you know if I ever receive it.

Hey Rettic, that link shows two different bearings, a NA5904 and a RNA5904. What is the difference between the two?

[DAVINCI]

The RNA5904 comes without the inner ring

Ok, tried to order this part na5904, the person at eb atmus is saying that this is a race only and the rna5904 is allso a race only, what part number did you use to cross ref. this bearing ?

[DAVINCI]

This is all ancient history, but I guess as new guys come on it bears repeating.

The NA5904 is the whole enchilada.

The RNA5904 is the outer race w/ needles, but without the inner ring.

This info I got from the NTN Bearings web site. Also from the KOYO engineering docs. BTW, KOYO was the OEM supplier for Yamaha back in the day.

I will ask him this question when he calls me back, but i dont know if this guy can give me this answer because he is calling the bearing mfg right now to check this out, witch is NTN i gess, i think what it is going to boil down to is weather NTN still is makeing this Bearing, it looks like that all atmus is a bearing suplyer

[DAVINCI]

Many of us, myself included have been down this road before. Don't waste too much of your time on it.

Well i got on this search and destory misshion and this is where it ended up.
Just talked to NTN and they said it was an active part number and said the last production run was in Oct of 2010, i ask if they had them in stock and he said what he could tell me was there was a good chance that they had it in stock, he said he was not allowed, buy the eng. department to give out any more information on what they had in stock.
