Bearing
Fault Kit
- Deliberately faulted bearings to learn waveform and spectra of classic
bearing defects.
- Learn about signal processing issues such as averaging techniques,
leakage, and spectral resolution on determining bearing faults.
- Perform experiments while increasing the severity of defects.
- Determine why ultra-high resolution spectrum is needed to diagnose a
bearing fault when fault frequencies are located close to multiples of
RPM.
- Learn how a large signal can mask adjoining low amplitude signals due to
spectral leakage.
The kit contains: one inner race defect, one outer race defect, one with ball
defect, and one combination of defects. The fault frequencies are very close
to the multiples of shaft RPM.
