The 3-Roll Troughing Idler is the most commonly used conveyor belt assembly, designed to support the belt and form a trough shape that increases conveying capacity and reduces material spillage during operation. It typically consists of one central idler and two side idlers set at trough angles such as 20°, 30°, or 35°, depending on the application, along with a robust frame for secure mounting on the conveyor structure. Installed on the carry side, this assembly supports the belt under load and can be customized in terms of idler diameter, length, bearing type, and sealing system to suit dust, humidity, and heavy-duty operating conditions, ensuring longer service life and reduced downtime.
