Could these be used vertically as guides for a table lift?

Yes, probably for load under 40lbs. Just remember the bearings do not fully wrap around the bar.

What does SBR refer to and which is best for a plasma cnc table?

Short base rail. I would see if they have larger one.. these would work if it’s a small cnc like a 2’x4’.

Can this be used for 3d delta printers as the vertical sliders?

It appears to me that delta printers use a different styles slide. My first impression would be the answer is no. These components soul have to be placed side by side to see off modifications could be made to accept what your suggesting. I am not familiar with delta printers. I did however do a little research. So to offer these as a replacement should be investigated thoroughly... Good luck, Len

Can these be used in an inverted configuration like a hanging sliding partition?

Yes they can. As long as the weight isn't to much. They will go side to side a little
