What psig are the most remote bearing pressures maintained at?

Explanation:
The key idea is that remote bearings need a steady, sufficient lubrication pressure to maintain the oil film across long feed paths. In this system, the regulator is set to around 14.5 psig, which provides enough pressure to push oil through any line losses and maintain lubrication at the farthest bearings without overworking the system. If the pressure were as low as 12.0 or 10.0 psig, the reduced pressure could cause insufficient oil flow to distant bearings, increasing wear and risk of bearing failure. Conversely, 15.5 psig is higher than the typical regulator setting for this setup and can lead to unnecessary flow and potential stress on seals or lines. So, 14.5 psig is the standard target that balances reliable lubrication with system efficiency, making it the correct choice.
