bearing smearing?

this bearing came out of a belt drive toyo pump. vibrations were showing BSF with sidebands of FTF, gSE spectrum shows it the best. I was hesitant to make the call for this reason since it wasn't showing to much in the velocity spectrums. not sure if it was to early to make the call or not? would this be an example of bearing skewing or smearing?Read More...

High Gravitational Envelope (gE value) in motor bearing

It is a 4 pole 2.5 MW motor. The vibration of motor is not very high (some high frequency peaks were observed). In acceleration spectrum , BPFO harmoics are observed , however no change in bearing temperature or current. In spectrum also peaks present at BPFO. The images are attached. Any suggestions for the problem?Read More...

HIGH VIBRATION IN GAS TURBINE

Hello experts The reason for this post is to know your opinion about the trend and the spectra collected in an MS 5001 gas turbine, I would like to know your opinion and to what condition or fault the graphics can relate. In this inspection only those graphics were obtained, the machine does not have a key phasor to know the phase, but even so I consider that a good diagnosis can be made. in my experience, the condition present in the turbine is attributed to an imbalance and thermal...Read More...
