Like another poster here, I ordered the vxb bearings and I'll indicate end play and shim. I can do a lot of fiddling for the money saved!!
I saw someone mention shims. I haven't been able to find these bearing shims anywhere. I searched all over McMaster and couldn't find. I googled, couldn't find. So, is it snip, snip with .001 shim stock or does someone actually KNOW where to get these. The local bearing shop just shrugged when I mentioned it!!
Oh, BTW, to the poster asking how they mount, it's back to back or face to face, so the angles counter each other. I've not seen a preference, but back to back seems to be the more common. So I guess, large to large, or small to small, but definately both the same way!!
