Hello All,

I kindly request for Bearing Info. for Timken Bearing 483/90091. This is the NDE Bearing for Nash Denver Vacuum Pump.

Thanks

Maha

I could not find a 483/90091. The only bearing that I could find listed in a Timken program that I have shows 483/472D or a 483/472. The only difference in the 2 is one is a double row.
Maybe this will help.
FTF 3.928
BSF 7.856
BPFO 8.777
BPFI 11.223

My database shows:
Timken 90000 series;
FTF: .428
BSF: 3.07
BPOR: 7.281
BPIR: 9.719

17 Rollers

If you're not sure, just take the number of rollers X 60% for BPIR and X 40% for BPOR then X rpm for the defect detection.

Thanks for the info.

Best Regards

Maha
