Brass or stainless tooth bars offer increased allowable profile loading options over the standard ATN® inserts during loading. The bolted profile is support by a bar that spans across the entire tooth of the timing belt thereby sandwiching the belts’ steel cords between the insert and the profile. The metal tooth connection technology may be useful in instances where the standard solutions are not strong enough, particularly for loading in the normal direction (perpendicular to the belt back surface.)
