Husaberg FS650e 05 Bearings

Can anyone check my bearings selection for husaberg? Is it better to use ball-bearing (TMB 206 JR2 C3
KTM 0625060206) instead of roller bearing on left side? All bearings are from NTN, but one of them is too expensive (NJ205), so I would change it for FAG. Are FAG berings reliable or should I use SKF instead? Thanks

Nothing necessarily wrong with FAG bearings. You should look at the Main Bearings thread written by Bushmechanic. Lots of valuable info in that thread. Specifically, SKF are fine bearings but the roller angle is a bit sharp as compared to the NEC bearings for use as mains. What you save in the short run by not buying the hybrid bearing sold by ktm (77330082000?) may cost you more in the long run. Check out the main bearing thread before purchasing and decide for yourself. If not the KTM hybrid bearing, I'd use an NTN or NEC tapered roller bearing before SKF. I don't know with regard to FAG.

Hi Sancho

The SKF is the better bearing. I have sold probably what? 200 sets without a problem but I can't stop people from blaming the bearing.

BUT, there is one thing you should note, KTM have STOPPED the NTN bearing and carried on with the sale of SKF.

this is tremendous news because despite the weight of vile comments against me I offer those two absolutely compelling facts;
KTM dropped the bearing
200 pairs sold no problems

essentially Sancho, the ends of the rollers have two dfifferent shapes. the SKF are square ended. 90 degrees. the NTN rise to the middle of the end ever so slightly - not much.

and now I offer you a simple scenario; your mother calls you and says; "Sancho, get over here and knock the front wall down, I will be putting up a wooden fence"

"OK, Mum"

you go over to Mum's with a 10LB hammer.

Sancho where would you first strike to bring down that wall? in the middle/top or on the very bottom brick? will hitting the very bottom brick bring down the wall or would hitting the middle brick?

well, the main bearing inner race has a wall at the end - a shoulder. I don't want to break that wall but the crankshaft will wander and the rollers will keep hitting it, infact they will smash into it a lot. so is it best that the roller contacts the inner race at the bottom or half way up?

Below is a photo of spalling on a customers inner race but you get a perfect view of the shoulder on the inner race that breaks off.

the other two photos are of the inside of a crankshaft. there is a curved dark area like the 'spike' on a heart beat monitor. this is where the pin leaves the inside of the crank. the carnk is very flexible. this means the rollers are always hitting the shoulder (the wall).

Hi Goose and Taffy,

thank you for reply. I bought a Husaberg FS650 05 and the previous owner did not take care of it, so I try to put him in order. I'm still studying everywhere as to what to do.

I found NTN bearing for a great price. I need the last bearing NJ205ECS42, but it is too expensive. I would like to replace it with SKF NJ205 ECP/C3 or FAG NJ205-E-TVP2-C3, but I don't know if the clearance C3 will be a good choice.

Is there any chance somewhere to buy a counter balancer bearing for a good price?

Thanks a lot

just to add something ''different'' be careful when you buy some bearing as there are cinese ones on the market with ''skf'' or ''ntn'' boxes

try to purchase them from the main distributor even if it can cost a bit more(not a lot)

ps. I use fag bearing on the 650
Thanks from bushmechanic, Rainerio and canolman
