Belt Sag

Conveyor belt sag also referred to as catenary sag, is based on standard catenary theory. Sag is expressed as the percentage height drop based on the tension between two conveyor idlers. These percentages are expressed as limits to this height drop, and thereby define the minimum allowable tension, during the applicable running condition, at that point. The table below is a list of design sag limits from various design manuals.
