My point was that the oil feed pressure to the bearing from the PD pump does not have any role in the resulting MOFT created inside the bearing. There is no supply pressure parameter involved in the design of a journal bearing. Only thing the supply pressure will do is cause slightly more flow through the bearing (above the bearing's flow from rotation) which can help keep the oil temperature down, which will help keep viscosity up slightly inside the bearing.

Don't need the link, I can write a book on the subject and probably know this as good as he does.
And this is not to impugn you in any way- this is a very complex subject and 99% of the people out there never encounter it in detail
This is an ultra fine point ( and crank bearings are a known special case not addressed in his article- they also have their own rules).
As you posted what you posted- that's 100% true but its incomplete and misleading due to all the special cases which must happen for it to be true and maintain trueness during the entire single cycle. ( and cant be explained in 3 lines)
This applies to a reciprocating application ( the special case)
Yes the bearing internals generate the pressure for the MOFT however the precursor is the pump ( in terms of volume and velocity) "pre-compress" the fluid in the pipe on the way there so its ready for the load zones unique to the tangential forces encountered under a loaded reciprocating action. ( this is the detailed part the internet articles don't touch)
If this did not happen, first the "slapping' of the bearing during the arc would simply "squirt" the oil back out so the boss tolerances act first as a shield ( to contain the moment) then the pump keeps force on the other end.
This is why during a failure analysis when the MOFT goes the impact looks like a half moon in path ( the textbook sign)
Even this brief bullet is leaving out a lot
This is not a shaft bearing where loading is constant ( which is the simplest form and whats commonly out there)
