so, i have collected enough rough, now it is time to get my equip. made. i am making a 12" drop saw and would like to add a sliding table so i can trim with the same saw. i am copying the design in the
pics and what i can not find are the u grove wheels (i think that is what they are called). some of the older slab saws use this kind of wheel, but i can not find the wheels as replacements on their
website. i could use linear bearings, however i do not know how fast they will get clogged with mud. the u wheels would also make removing the table for cleaning much easier. i would like to use 3/4
to 1" (19 - 25mm) shaft for the ways, as i have these sizes in both stainless steel and hardened steel. i am open to alternative methods for doing this on the cheap.

I think the bearings you are looking for are called "guide track rollers" or similar. I repaired a rowing machine for a mate many years ago and had to buy a couple.

Go to a tool rental place and look at how the table on a masonry saw works. Small narrow "pulleys" ride on the upper edge of an angle iron. While you're there, ask if they have replacement wheels.
I'd take a photo of the table and rails on my Diamant Boart tile saw, but it's still packed away for the winter and I'm not allowed to lift over 10lbs right now.

Have a look at V-groove rollers, Amazon has several different ones available. I couldn't get a link to come up. These would be my choice of type of rollers for your application.
