The number of vehicles (OEM production)on today's roads that run a "Green Bearings" configuration number in the millions, green bearings have been as hard to accept for the Mopar crowd over the decades, just as hard as accepting disc brakes, never mind 4 wheel disc brakes!, OD transmissions, mini starters, one wire alternators, rebodies, roller cams, non numbers matching drivelines, color changes, or a clean change of underwear!

Valid point, however one must consider the size of the bearings, the weight of the vehicles, their usage etc. IE: An equally sized Timken will easily surpass the longevity of a Ball bearing. That is not to say that a LARGER ball bearing cannot equal the longevity of a Timken.
But a Ball Bearing cannot equal the service life when sized the same and subjected to the loads they were not designed to be subjected to, PERIOD!!! Just because the ID and OD match does not mean they were designed for the same use nor will they perform the same.
