Ultrasonic Bearing Grease Management with SDT: 70% of Points Over-Greased
SDT multi-plant studies: switching from grease formulas to LUBExpert found ~70% of bearings over-lubricated, 15% under, only 15% correct. How ultrasound sets dose and interval.

Why calculators fail
Fixed grams ignore load, temperature and early defects. Ultrasound measures friction — both too little and too much grease raise the level.

|---|---|
| Over-lubricated | ~70% |
| Under-lubricated | ~15% |
| Correct | ~15% |
Process: baseline in UAS3 → grease only when needed → stop when dB rises → GOOD/BAD/SUSPECT. Entry tool: LUBEChecker; routes: LUBExpert.

What Is Acoustic Bearing Lubrication — and Why It Beats the Calendar
In plain language: acoustic (ultrasonic) lubrication means adding grease based on friction level, not only the date in the PM schedule. How it works and who it is for.

LUBExpert Case: Greasing a Cement-Plant Fan Exposed Bearing Failure Early
SDT cement-plant case: calendar greasing dosed 50 g every two weeks. LUBExpert Static cut dose to ~16/14 g and, with rising friction plus vibration, caught cooling-fan bearing failure before unplanned downtime.
