Replacing IMS with Original bearing

I wanted to address this separately.
The races and cages of the ceramic IMSR are still ferromagnetic and will trigger an IMS Alert. We have carried out this specific testing all through 2011.

BUT in applications where the IMSR is employed the IMSG is more useful in alerting the driver of the other ferromagnetic wear metals within the engine.

Won't the heavy metal cage be slower accelerating/decelerating than the ball bearing itself? Causing the ball to bang the against the cage, accelerating wear on the cage? Eventually banging chips in the ball itself as the ceramic ball sharpens the the edges of the metal cage?

I think that is why bearing companies use nylon or Teflon cages with ceramic balls as they are lighter and can keep speed with the ball itself.
