A ball bearing run at very high speed is going to loose the cage before anything else.

In a two stroke, whatever comes off the bearing goes up through the engine. The Melmide in theory doesn't hurt anything. But I put new rings in after loosing a plastic cage.

When you start to loose the cage, you will never know it unless a piece of the metal cage start tearing up the piston.

With the plastic cages, the saw may run OK for a while but will suddenly stop when all the balls get on one side and the crank hits the crankcase.
We should share what we know... someone may learn...
That knowledge can live after us... and that "Pays It Forward".
Be all that you can be . . .
