The thinking is to just try to keep a low level of oil behind the bearing, just a supplement to the oil feed the engineers already provide. This would be a very low pressure, low volume pump. I imagine much less than 1 psi and on the order of 1 liter per hour. I drew the seal a little better to show how it is trimmed near the center race to hold oil until it reaches a certain level.
I am looking at this as more of a drip system, not a fire hose.
