Instead of making bearings I would look at what Igus and others have to
sell.
They are not that expensive and you have plenty of other things to do.
Regenerative Vacuum blowers work well for vacuum hold down work. They
are still power hogs and quite noisy without mufflers on the outputs.
They are sometimes sold on Ebay for not much since few people know what
they are.

Hello Gregg,
Something like this is what you have in mind?

It's a nice feature, and seems cheap and not hard to implement. That's
probably the way I'll do it.

You could make the vacuum table with several zones, connected with a PVC
pipe manifold and ball valves to close off sections you're not using. That
would be easier than keeping stuff around to lay over unused sections of
the table.
