The bearings don't make oil pressure, they retain oil pressure.
The oil pump delivers a given amount of oil per revolution. The faster it turns, the more it pumps.
When the bearings wear, or the pump wears, (really a combination of both), there is not enough volume of oil being pumped at idle to fully pressurize the system. The oil takes the path of least resistance, so any excessively worn component dumps the oil back to the pan instead of sending it everywhere it needs to go.
Are you sure the problem is really low oil pressure, not a defective gauge? Might check it with a known good mechanical gauge.
In rare cases the problem can be a defective oil pump, stuck open relief valve, or fuel contaminated oil.
