Help needed !!!!

OK, remeber I wanted to install the camshaft on roller bearings?

OK.

The project is almost done.

Of the 3 contact points of the camshaft, 2 of them are already done or waiting to be machined, but there is one point (the one in the middle) that needs a special solution and I CANT find the bearing I need.


The left sliding point is done, hand machined by me..


Here you can see it with the propper neddle roller bearing that will work there:




The extreme right sliding point is waiting for being machined.
Here you can see the selected bearing:




MY PROBLEM is the MIDDLE sliding point.
I cannot install a normal or standard bearing because I have the cams or the timming sprocket.

This is the one:


What I need is a SPLIT cage and SPLIT bearing type.
Something like this:




This is no INVENTION from my side.
This is something that has been going on for a while in mechanical engineering.
There are articles about this (read this one from NTN Bearings )


HERE you have another article.

I already sent an email to NTN and had no answer.

I really need to have a 25mm Internal Diameter Split Cage roller bearing, but no one seems to know where I can find one.

I guess my last choice will be to contact a Bearing MAnufacturer and see what I can find.

The other choice was to buy an OPEN cage bearing, and then using a steel bushing, fabricate the external split race for the bearing ...

I really DO NOT want to use steel bushings in this sliding point.
The whole Idea of constructing this bike was to find alternative technical solutions in order to achieve more torque and durability....and the CAmshaft bearings are the Achilles hill of this bike...


PLEASE, if someone knows where I can find this type of bearings, let me know !!

Forgot to mention:

None of the machine shops I have presented the project (of installing Roller bearings in the camshafts) accepted it.
So Im making it my self.

Ill hand made one (it will take me a long time), and once Ive done it, Ill use it as a model in order to replicate it...

Yes, I Im in contact with a bearing manufacturer now. They propose to use a YAmaha 75HP 2stroke marine engine bearing (only split roller cage),and I can manufacture internal and extrenal races.....
Lets see what turns out...

My life is a collection of NON Bolt on Mods....

I'm based in Australia and travelling to BA in mid December so if there are some small items (you know customs there) I could bring them over for you. I'll be based in San Isidro.

I suppose Harbor Freight isn't readily available either, but they have rubber safety tread with an adhesive backing. Cuts easily with scissors, might be a good choice for some knee pads. I've been using it for 2 years on the top of my panniers, it fades a bit but holds up amazingly well to sunlight.

Ahhh...entonces entendes la combinacion de colores y el Tribal del Toro en el tanque, no?

The Mini Dakar is simple.
Ship the bikes to jujuy, take a plane to jujuy, pick up the bike in Jujuy, hit the road straight north.
Hit bolivia, Salar de Uyuni (spend a Camp night there) , go to La PAz, ride the DEATH ROAD (LA ruta de la muerte) , then north to Peru Through the Mountains, to Cuzco (several nice sightseing parts in the middle), Matchu Pichu, keep north until we touch NAzca,
Change course to the West, once we see the Pacific, change the course to South East, cross country, Chewing Coca, until we reach Salta.

Thats it.
im afraid I havent more details, Im not the navigator, Im the "Trash bike" (the last one in the line, who has the mechanical skils and is fast enough to catch the first one if necesary).
