I was thinking the same first but the axle will not move the to other direction unless if i walk backwards with the dirtbike which wont be with high rotation speed and allot of forces,Id go back to without it as its not going to work as in theory...
When you sandwich one of those between two objects where one side spins and the other is stationary and pressure is exerted youll have two forces at work...One force will try to spin the bearings on their axis and another force is gonna try to spin them to the side..Only way to contnteract the action is by stacking two bearings with a thin shim in-between...
The side spin will prevail and when that happens one side of the bearing will experience the bearings spinning in an opposite way adding a stymie to the spinning action and damage to the bearing....
It would just be better trying out using some thinner teflon or low friction stainless shim washers and seeing how its gonna work first.....
infact the clutch should neither be engaged when the engine is running at stationairy rpm's..
I also have cutted a ring grove in the sprocket so the bearings sit a bit integrated in the sprocket/clutch.
And it spins great on the shaft now!
I did ran in to another issue now though that i saw comming to be honest,
Which is the chain who is going diagonal..
This could be fixed by integrating the thrustbearing deeper in to the sprocket side of the sprocket/clutch.
I will make some pictures soon of this issue.
