The shaft is a standard 3/8 diameter. The original bushings will last forever if oiled...the felts need to be oiled well.

Where were you and your super useful comments when I was working on trying to figure this out. :) So yeah the 9.5mm is 3/8 inches ID...and the 28.5mm is 1 1/8 inches OD....and those look to be more common and easily found. ie a quick amazon search showed this one which may be a bit too thick, but still is similar sizing: 1614-2RS 3/8“ x 1-1/8” x 3/8" (ID X OD X Width) That would take more measuring to figure out the width as i do not remember offhand the thickness needed given the spacing...and did not write that down, For some reason since these were 'modern' fans I figured they would be all metric and so looked that route. Should have done the sae sizes too. Thanks. Once the bearing dries out and cooks the shaft, ie leaves a burn/whatever mark on it, that would indicate the oil dried out. In that case if you wanted to go that route the shaft and collar would need cleaned thoroughly and then the oil re-added. Do you know by chance what kind of oil should be used? That would be another way to go for fixing these fans.

@@josephkrug8579 I have taken apart at least 20 various fans/motors with those type of bushings. There has been not one single case where cleaning up the axle/shaft and the interior of the bushing of any dried oil and then oiling well that the motor/fan has not worked fine. They aren't high tolerance bushings. Just a light weight household 10-15 wt oil. 3-in-one is fine....but...be aware...they do make a heavier 3-in-one that may be too thick.

@@brianroberts4349 Thanks, I heard from others that 20 wt non detergent oil works too. It is good to know the options for sure. As I know lots of other people just throw them out and buy another one, which I would prefer to not do.

You can lube the bearings in place on some motors using SUPCO zoom spout oil

Thanks, I heard from other people that 20 wt non detergent oil can also work. It is good to know the options. I know that you should NOT use the 3-1 oil from some people, and others said it may work ok, so it is good to know the various options. :)
