Thanks guys.

Although nothing hit it on the head, you got me looking in a new direction.

I tracked down something that was not exactly what I was thinking about, but
should work.
It is called a "two bearing housing" and is designed as a pillow block for
big honkin' fans.


There are also bearing units intended for supporting screw conveyors:

Very rugged, but rather expensive. $229 for that size last time I
bought one.

For less than $100 Misumi will make pretty much anything you might
need, as long as a metric bore is OK, and you don't need set screws to
lock the shaft.
