Flathead bearings - red/blue sizes?
Hi All,
I'm going through a few boxes of flathead bearings and found several with odd dimensions. For example, I've got a set labeled "ICM-6333-A Red .0852-.0855 and Blue .0855-.0858" Can anyone explain the color/sizing? I've never run across these before and am not finding anything in my books. |

Std bearing thickness is .0852, so these could be used on a slightly undersized journal

Ahh, thanks! I wasn't considering the shell thickness. Were odd journal sizes really that common? I've come across piles of bearings over the years but never the reds and blues.
