Download Sound File of Bearing Lubrication

Using ultrasound detectors to re-lubricate motor bearings may be the most important NEW application for ultrasound technology. Take a look at the time waveform below and you can see the before and after effect proper lubrication has on a bearing.  Using the SDT 170S+ Lube Tech Kit and a simple recording device a technician captured the rough growling sound profile of the bearing (48dBuV) prior to giving just the right amount of grease. The instant the grease reached the rolling elements friction was reduced and the bearing's ultrasound signature became quiet. The 170S+ digital readout showed 32dBuV, a drop of 16 decibels! Not lubricating this bearing in a timely fashion would lead to catastrophic failure in the near term. Lubricating without the 170S+ Lube Tech Kit may have resulted in over-lubrication, and... catastrophic failure in the near term.

You've arrived at this page because you wish to receive an electronic copy of the "lube" sound file represented by the time graphic below.  The sound file was recorded from an SDT 170 ultrasound detector connected to a grease fitting on the drive-end bearing of a 175 HP electric motor.  The sound file and graphic represents the affect of one shot of grease reaching the bearing, as heard through the SDT Acoustic Lube Adaptor.
