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.

Over-greasing damage

Why calculators fail

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

Before ultrasound Share
Over-lubricated ~70%
Under-lubricated ~15%
Correct ~15%

Dose distribution

Process: baseline in UAS3 → grease only when needed → stop when dB rises → GOOD/BAD/SUSPECT. Entry tool: LUBEChecker; routes: LUBExpert.
