Neither, of our 5x10 routers have any support on the long table screws (12 ft long). But they are large diameter screws, secured, fixed and stretched in position with a rotating nut moving the table. I think rotating the nut rather than the screw helps a lot with wip.

Greetings, I am upgrading my machine to handle a full 4x8 foot board of material (and 5 feet of Z!). The new table is 5x9 feet. I just received my 3-meter 25mm supported rails and 25mm C7 ballscrews. I am sure with a 10-foot span that the horizontal ballscrews will sag a little from gravity. Is this much of a concern? Does anyone know of a trick to put some kind of support in the middle of the span? I can't think of any practical way. Thanks!
