Key Takeaways:
Daily monitoring of supply pressure, oil flow, and film thickness catches hydrostatic problems early—before accuracy is lost. Consistent readings are the sign of a healthy film.
Three Numbers Tell the Story
In routine operation, three readings summarize hydrostatic health: supply pressure (is the pump delivering 1–10 MPa as designed?), oil flow (is filtration passing enough volume?), and film thickness (is the 3–10 μm gap stable?).

Building a Baseline
Record these values when the system is known good, then watch for drift. A slowly rising flow with steady pressure can mean a widening film from wear or contamination; a falling pressure points to supply or restrictor trouble.
From Reactive to Predictive
Because the film degrades gracefully, a monitoring routine turns maintenance from emergency repair into scheduled service—protecting the sub-micron accuracy and infinite-life promise of the bearing.
