Does anyone have access to the deminsions for calculating fault frequencies for a Timken 33213 Bearing. My CSI database lists the 33212 and the 33214 but skips the 33213. We have tried the Timken website but not having much luck. Any help would be appreciated.

Thanks,
Ronnie Lynn

I don't see it either in my Entek database but there is a listing for 33210 series which may be dimensionally the same whereas the last digit 1-9 represents a change in only a single dimension such as width so here they are. They're probably close enough to get you started.

FTF - .43
BSF - 3.42
BPOR - 7.745
BPIR - 10.255

vibbase,
Thanks, I followed your logic and compared the 33212 and the 33214 to see how close they were. 33212 has 18 rollers and 33214 has 19. All the other dimensions vary also but it does get you close enough to estimate the range of the different frequency calculations. I guess this isn't a very common bearing.

Thanks,
Ronnie

Ronnie, our local brg rep got the following info from Timken:

17 rollers
FTF .425
BSF 3.17
BPFO 7.222
BPFI 9.778

Doing a quick scan, it appears that TMK 32212 is the closest match in my RBMWare dbase, CSI# 1444. If you like, I can fax you the info I have.

Hope this helps.

Michael,
Thanks alot. That does help but does he have the deminsions: ball diameter; pitch diameter; contact angle and you have given me the number of rollers. I can use the calculated frequencies you gave me but if I had the deminsions, I could put them into my bearing data base and set them up in my fault frequencies.

Thank You,
Ronnie

Michael,
Forget that request for the bearing deminsions. I was able to use the calculated frequencies and store it. Never done it that way before. Anyway, thanks for the info.

Thanks,
Ronnie

Hi Ronnie-

You should check out The Bearing Expert Interchange and Vibration Database at http://www.sourceindex.com. Go to DEMO to try the database. You will get a few free searches. You part number is in there with dimensions.

smartini,
Thanks, I will check that out.

Thank You,
Ronnie
