I just returned from the Design and Manufacturing trade show here in Southern California.

I saw several examples of belts used for moving things in place of ballscrews. The one I was most interested in was a stainless steel strap with percision holes in it. It ran on plastic pullys with screw heads that corrisponded with the percision holes in the steel belt. The salesman told me it would hold .003" in a foot.

It was much more affordable than the rolled ballscrews I need for my machine.(y is 74" long and x is 63" long)

I would like to hear your thoughts.
Any infor on belts used for this purpose would be of interest to me.

As allways, thanks.
