Ultrasonic Bearing Grease Management with SDT: 70% of Points Over-Greased

Source. SDT “Bearing Grease Management using Ultrasound” and LUBExpert / UAS3 practice.

Why calculators fail

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

Plant data

Before ultrasound	Share
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.
