Here are some intersting tables on Rounthane. Notice that you can see the extra load the stretching will put on your motor, which guided us into our new conveyor motor setup for Atlanta. Previously, we just guestimated everything with conjectures that a motor would or would not work. This data, PINK's recommendation, and the lack of necessity to weld the belting are all of the reasons we're redoing our conveyor with it for Atlanta.
Quick question though -- is the polyurethane cord on McMaster the same as the Rounthane? Usually mcmaster mentions the brand name, if there is one, in the product details.
