Do You need 3/8 ID or 1-3/8? I have some that are about the same ID as skate board bearings, at around .806 or so. They are only 1 hole flange though. They may be good using 2 of them per spindle, for a spray booth at low RPM, if that's what you need them for, but I don't know about anything too high speed. Here's what they look like. May not work, but If they will work for You By chance, then Your welcome to some, just PM Me Your address. Greg
Cue crazy thanks for the offer. I wanted it to be pretty ridged mounting.
kydartmaster thanks forgot about mcmaster been a while since I ordered from them. Like 2-3 years ago. They have everything I needed. I opted for 1/2"
