There is a company called Brecoflex that offers belting in continuous
lengths.

Has anyone thought of just using the generic 5/8 rolled ball screw? It comes
in up to 12 ft lengths and you can get the double preloaded ball nuts, make
up a thrust bearing plate that would anchor to the carriage and the ball nut
would be driven by the motor instead of the motor driving the screw. The
ends of the screw would be mounted under tension thus eliminating the
problem of lead screw whip.

If there were enough people interested in something like this, the group
could get together and design a mechanism and have a bunch made reducing the
cost with a volume purchase. Just a thought....
