Another IMS bearing thread

[Jake Raby]

Carry out these experiments within an engine and you'll see that your observations change.

Over time we have found that not just the strength of the cage matters, but also the weight of the balls and the cage. This is because the inner race is parked and the outer race is rotating, among other things.

Of course, the only real solution to the issue is removing the balls and the cage completely from the equation.
