In article , Gunner says...

Ive seen a goodly number of arbors which included their own bushing
AND bearing which is designed to go into the arbor support. I did a
quick search but was unable to find an example on the net.

The hardinge runs that way. There is a bearing integral
to the overarm support, and a slightly tapered bushing
inside of it. The end of the arbor (tapered also) fits
right into that.

I've also seen older machines with plain bronze bushings
that the arbor end slides into.
