Conveyor Belt Idlers Conveyor belt idlers from Truco help provide motion to driven conveyor belts. They also assists in applying angles to the belting to achieve different surcharge angles up to 45°. Conveyor idler sets, made up of rollers and a frame/drop-bracket, are a critical part of the conveyor drive design. The troughing idler sets consist of two or more rollers with bearings for smooth rotation and are supported on a frame. The return idlers are supported by drop-brackets. Both troughing and return rollers are supported across the width formed by the conveyor stringers. The idlers support the belt and the load of material it carries, which translates into smooth and efficient movement on the conveyor belt system. This support plays a huge role in preventing conveyor belt sagging, stretching, and possible failure. Conveyor idlers are rated according to their load-carrying capacity and bearing life, which is calculated with precision. Classification is done according to the type of service, operating conditions, belt loads, and belt speed required.
