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?

thanks for the reply. I have review some bearing photos and thought it might either be smearing or skewing in my opinion. this pump has been in service for about 2 years it uses ISO 150 oil. there are 4 pumps just like this one and they all seem to show in gSE BSF with sidebands of cage on the inboard bearing.

.206 IPS overall in the envelope spectrum.

no this is just a belt driven motor/pump sorry about the pictures not being clear. they are suppose to be BSF frequencies with sidebands of FTF. I'm also wondering if the belt frequency has a lot to do with the issue. possibly over tightened

According iso 15243 

I think it seem abrasive wear cause of contaminated lubricant.
