Good morning all.... What's the general opinion on Main bearings. Most people now know that "superblend" bearings are the only option for a successful rebuild, how ever the word superblend ( as far as I know ) is the name given at the time by the company who invented them... FAG of Germany. My enquiries to Norton parts distributors always comes up with just that... FAG SUPERBLEND #NJ306E. If I ring local distributors they mostly quote on NSK (JAPAN) or SKF (....). The bearings that came out of the bike are FAG NJ306 E India, (now made in India)... Does it really matter, surely they are all manufactured to a standard... Perhaps Japanese is now better,??? The prices are about the same... Does any body use anything other than FAG and do they need to be Brass cages ...AC.
 
There are other options of equal quality, I don't recall the brand name, but they sell for less than the original F.A.G. brand.
 
Aw come on guys, is anyone going to tell him it has to do with which oil is being used...
 
NSK and SKF make good quality bearings. I've used NSK superblends for my 750. The ones I used had steel cages for the rollers whereas the FAGs use brass. People will tell you the brass cage is better, but, hey the steel ones worked OK for me.
 
I run a FAG NJ306 on the drive side with a SKF hi load Ball on the timing side, this works for me.

"Superblend" was the original British made R&M ( later RHP) 6/MRJA30 bearing.
 
Thanks guys. I've bought a set of Fags"... Of the 5, Bearing distributors that I spoke to here, none had heard the term Superblend. The ones that came out of the engine had come from RGM England so I'm happy with that. For what it's worth, they varied in price from $59.00 to $150.00 each. Pays to shop around eh?.. L.A.B. You're probably right...AC... P.S. Got a good set of second hand FAG for sale.
 
I believe that the 'E' suffix indicates "extended" duty or some such, and the only versions I could find were FAG. If they cost less than $100 US each you probably have the wrong one.

Second hand fags for sale? Different connotations depending on where in the world you reside (and your level of maturity--or lack thereof), I guess.. :lol:

Yes this was set up of past dragsters and how i did Ms Peel for extra rpm head room. They held up hundreds of rpm over red line, once 1000's over.

Superblend bearings.

Take a look here.

NJ - semi-locating roller bearing (as opposed to the non-locating NU design Norton used together with the -fixed- ball bearing)

3 - series 3 which specifies the cross section details (width and height of the races mainly)

06 - 6 times 5mm gives the ID -> 30mm , together with the cross section this defines the OD as well

E - Increased capacity design

C3 - internal radial clearance bigger than STD

M1 - brass cage (as opposed to TVP2 polyamid cage which is what you usually get if you don't specify the cage material). I'd be a bit reluctant to use a PA cage as it is only safe up to 120°C - not much safety margin left.

If you want to use another bearing manufacturer just cross check the design details with the codes of the competitor. If the load rating, the internal clearance and the cage design are similar I can't see a reason why a standard part couldn't be replace by another standard part.

EDIT: SKF table about radial clearences, e.g.
 
Yes Hobot i also used the SKF ball bearing on the methanol burning supercharged race motor i raced some years ago and never had a related failure.

Hmm, very encouraging to hear. I've been bitten by over rev event so rev limiter is a must on Ms Peel shootting for torque over hp, but for some record attempt I may have to put 11 balls on the TS to let the crank ends flex over 8 grand. For my ordinary factory Combat, just went with no brainer BI vendor superblends.

Off subject but was your boosted race engine able to start and idle ok? What kind of race event allows boosted Norton or any boost for that matter? How high did you go?
 
In Aust.... FAG's are bearings..... usually round.
fags are Cigarettes..... smelly things that give you cancer
FAGS are..... Gay men..... men who enjoy the close company of other men. Not that there's anything wrong with that.
Just to keep this Norton related. I enjoy the company of my wife, children and Motor cycle called Norton.
Oh yeah and my Pennsylvania Long rifle, in .50 cal...AC.
