I have seen a few posts asking this information, but no answers. Just thought id post in one more time. Anyone have a bearing part number for the F390599/ 1" id wheel bearings? I have seen alot of posts about how bad the HD bearings are failing. Would like to up grade to something a little better.

 

That F number is a part number. You should find that any bearing supplier can identify it and offer different brands of bearing.
