Listen and Wait … When Greasing Bearings

Condition based lubrication programs rely on ultrasound data collection to alarm when re-greasing is required. Our advice:

Alarm bearings for re-lubrication at 8-10 dBµV over baselines
Apply grease slowly while listening and measuring ultrasonically
Grease... then wait. Don't hurry at the expense of doing the job correctly

Your target is to return the dBµV values back to baseline. The 8-10 dBµV rule works in most instances, however statistics are a poor substitute for common sense.
