I am thinking about buying anti-backlash Acme Nuts/Screws from:
http://www.kerkmotion.com/products/s...s-overview.asp
They listed the entire assembly as having a dynamic load of 100 lbs. My question is what does dynamic load mean? Is this the maximum amount of force the Acme screws can handle while pushing the table side to side? Or, is it the amount of weight of the moving table itself and anything sitting on the table.

I am concerned that the max. dynamic load might not handle my 5' x 7' router built from 3"x3"x0.25" mild steel tubing. I plan to use rapid speeds of 200-300"/minute.
