Timing Belt for 10.5 foot travel axis?

[DanOSB]

do you have any suggestion which timing belt to use for 10.5 foot axis and we want it to be pretty accurate... and dont want stretch back n forth too much when the gantry is sliding.. the gantry itself with everything on it will weight about 200 pounds and there is no work force (cutting torch/plasma) when cutting the material.. max speed would be about 500 ipm

That's getting pretty long...

Would roller chain work in your application?

You may want to consider http://www.brecoflex.com/ I have used their continuous belting in those lengths, they are made specially for those type of applications.
