Blaster vs Superjet midshaft bearings

[96superjet]

First: I checked all through the forum first, including searches from Google and only found one thread that was asking the same question with no response.

When I was building my current 2004 SJ it came from salt and the rubber around the midshaft was toast so I just grabbed a midshaft from a Blaster that I wasn't using. After three years of use the splines blew out (I know mis-alignment). For what it's worth I now have a Cold Fusion alignment tool. When I was tearing apart the de-splined Blaster midshaft housing I swear the bearing was different then the ones I'm used to seeing in a Superjet (problem is I must have pitched the bearing and now I can't go back to reference).

So I did a quick search on OEM parts finder and this is what I came up with.

As you can see the bearing part numbers are different even though the housing part numbers are the same. In the past I have always purchased 6205 RS premium sealed bearings off eBay for Superjet midshaft builds (you can get like 10 of them for 20 bucks shipped). So... is there a difference between bearings in Blaster vs Superjet midshafts even though the housing is the same unit???

Ha... Just found the bearing I was speaking about. This is what came out of a 1995 Blaster mid shaft housing.

Blaster is the Dbl row bearing that cost about twice as much.

Reviving an old thread here. But this seems interesting.

So for any of you bearing experts out there, what are the advantages of the Double Row bearings vs the Single Row that is called for in the Superjet.

slightly off topic but are the Blaster Midshafts different to the stock superjet?

If you look at the microfiche above, it's the same housing.
