Which unit is used to express most remote bearing pressures in this system?

Explanation:
Gauge pressure is what matters for the pressure that actually drives lubrication and operation in a bearing system, because it is measured relative to the surrounding atmosphere. This makes it the most practical and informative way to express remote bearing pressures. The unit that communicates this directly is pounds per square inch gauge (psig). In contrast, psi without specifying gauge vs absolute can be ambiguous, since it could be interpreted as absolute pressure. Metric options like kPa or bar express absolute pressure or different reference standards and aren’t the typical choice for expressing remote bearing pressures in this context.
