castile combustion blower bearing specs?

[Countryboymo]

I was thinking of replacing the bearings in my combustion blower and wanted to order ceramic bearings. I do have calipers inside and outside micrometers if no one has the sizes. If no one has the dimensions I will take it apart and wait for the bearings to come in.

The blower is fine other than it is starting to get noisy.

Somewhere I have seen those dimensions posted here. It's a pretty common metric size. I want to say it's the same as skateboard bearings but not sure. Please post the dimensions when you get them because I wouldn't mind putting a set or two on the shelf.

I fired it up tonight and it is in the basement on high. It is starting to get pretty obnoxious. I think boca bearing will have them after I find the size. I might buy a couple extra sets if anyone else is interested.

Likely a 608S bearing.
