the problem is no other bearing inside a motor is sealed like this under such load.
ever other bearing is directly oil fed, or in a splash or submergence zone.

Not even close. Of the many we have pulled out, nearly every one were devoid of any grease or grease remnants, and all had oil in them. Of the ones that were already "on their way", both the balls and races showed signs of galling and excessive heat, but again most had just clean oil in them, not "slime" or anything else left over from the factory grease.

The question you need to be asking yourself is why the steel bearing needs a pressurized oil feed, when the some nearly 25,000 installed ceramic hybrids do just fine on the oil mist moving around inside the sump.
