High cycle double flange linear bearings from 80/20.

I'm building a 3 axis mill, 24-36"x24-36" working space (yet to be decided).

Ive seen precision linear rails, as well as the matching bearings but if i'm already using 80/20 (3"x6" 15 series #3060) should i be able to use these since they already slide on my existing frame so i can save money? I was going to use them on my x and y axis if so, but was uncertain if they have any play in them or what there wear life is.. Page 326 from 80/20's catalog. All the engineering specs are on page 343.

Part Number# 6834 $86.65 a piece.
If these wont work, anyone seen a linear rail made to easily bolt up to the T slots of the 80/20? Thanks a lot guys/gals!
Any help would be greatly appreciated!
Thanks!

Have you tried checking out IVT?

I included pictures of something I had done as a sample. It's not exactly comparing apples to apples, but it gives you an option of something else that's out there.

Thanks for the tip looks great! I'm just going to bolt linear rails to a .250" aluminum plate table top to take the complexity out of it.

Our rails will bolt directly to metric T-slot extrusions and can also bolt to fractional T-slot extrusions by drilling a few holes in the aluminum T-support.
