The troughing idler rollers feature a central roller with a horizontal axis of rotation, while the two outer (wing) rollers are angled upward, typically at around 25 degrees. Troughing occurs only with the top idler rollers and not with the bottom ones. Excessive troughing angles can cause permanent damage to the belt.
