Can you ask a more specific question? The following will clarify why I am asking.
It seems to me that the bearing is under load so long as the engine drive chains are moving. I would think the substantive issue is just how much load does the bearing bear under different operating conditions. The hypothesis I am about to advance is pure educated guessing on my part.
My theory is that forces create load - centripetal due to rotation and vibrational. At constant RPM, the bearing experiences some degree of load, say X. As acceleration increases RPMs, I think the loading increases as the chains increase rotational speed of engine components. At higher RPMs, however, the vibrational loading component decreases because vibrational amplitudes don't have time to reach their full heights.
