Troughing idlers are bolts on brackets that hold 3 rollers in a troughed configuration. This is to guide the belt and form it so that it holds material in and supports bulk loads. Using idlers reduces friction and limits the wear on the belt in dirty abrasive environments. Fluent Conveyors offers many different types of idlers including: CEMA rated, mine duty, return, self-aligning, channel inset, equal troughing, impact, unequal and many more.
