I have just had a piston pump installed that has INA bearings. Could someone help me out with the fault frequencies for the following bearings.
INA - F-207407.2 NA
INA - F-204754

Pump will be operating at approx 1480 RPM
Not sure why there is .2 in the 1st one.
Got these details off the pump suppiers here in Aust.

Thank you in advance.

Hi David-

You should check out The Bearing Expert Interchange and Vibration Frequency database at http://www.sourceindex.com. Look at their DEMO, you can get a few free searches on the database to try it. International Source Index, Inc. will also assist you over the phone.

Hello
I've also have Bosch-Rexroth piston pump installed and it also has same bearings.
INA - F-207407.2 NA
INA - F-204754
But I couldn't find any information about their fault frequencies even from the web site given by smartini.
have anyone find something about those myth bearings?

Hello Gentlemen-

Thank you for following up with International Source Index and The Bearing Expert. The bearing numbers you have referenced are OEM part numbers and that is why we are not able to provide you with frequency data. Can you get dimensions on these bearings? If so, let us know and we can assist you.

Dave
What is the pump information.
Brand, Model,
Piston etc
The INA bearing details I have does not have the ones you are after.
Do you have the bearing to measure dimensions?
Petri

Your frequencies are (based on 1 hz):

F-207407.2 NA
BPFI 11.062
BPFO 7.938
BSF 2.963
FTF 0.418

F-204754
BPFI 9.056
BPFO 5.944
BSF 2.310
FTF 0.396

It's a bit late from your original post, but hope it helps.
