Bearing Frequency Calculator

Bearing Frequency Calculator

Bearing Frequency Calculator

(OP)
I am looking for an ACCURATE calculator software supplier for bearing frequencies. I currently have The Bearing Expert from International Source Index Inc. and am finding some serious descrepencies with between it and manufacturers info. i.e. - # of rollers,dimensions, etc.
Any suggestions?

RE: Bearing Frequency Calculator

Look to software called Kuegellager (v4) from University of Aachen in Germany. At least for angular contact bearings it is excellent match to real world measurements.

RE: Bearing Frequency Calculator

each manufacturer of bearing got his own internal construction for bearing
for FAG bearing contact :

there are friendly

RE: Bearing Frequency Calculator

You can easily write your own calculator using Excel.  You will need to know the internal geometry of the bearing, which can be obtained from the manufacturer.  I can send you the spreadsheet we use for doing these calculations.  If you have SKF bearings, they have a frequency calculator in their web site tools.

RE: Bearing Frequency Calculator

Why do fault frequencies change:
1 - bearing manufacturs may periodically change their bearing designs slightly.  The SKF6308 that you buy today may not have same fault frequency as the one installed in your pump 5 years ago.
2 - Bearing fault frequency depends upon contact angle which in turn may depend on loading.  Can change for example with changing load on a pump which changes the axial load on the bearing.
3 - Extreme wear can have a slight effect.

RE: Bearing Frequency Calculator

My comments about load and wear were addressing slight deviations in fault frequency - perhaps 1% or less.  If you are talking about bigger deviations these are probably not applicable.
