Use HD Technology to Manage the Risk of Bearing Faults
Overall vibration catches bearing damage very late, when there may be 0.1% of the bearing lifetime left. Traditional vibration, let’s say systems with poor signal-to-noise ratio...

What Is Shock Pulse?
The shock pulse method was invented in the late 1960s. In rolling element bearings, there is a phenomenon where electric waves, or elastic waves, or shock pulses, or impact signals, are...

Resonance Solutions: Reduce Exciting Forces
We've confirmed resonance after collecting data. Now, we need a solution. Let's go back to basic physics; we can focus on the frequency or the amplitude...
