Abstract
A troughing side idler for use with a belt conveyor having upstanding first and second side walls. A first troughing side idler is secured to the first side wall and a second troughing side idler is secured to the second side wall. A horizontally extending medial roller extends between the first and second side walls for cooperation with the side idlers to shape the conveyor belt into a trough. Each of the side idlers includes an idler roller having a shaft which extends upwardly and outwardly through inner and outer bearings which are secured to a bearing bracket housing which is operatively secured to the associated side wall. The upper outer end of the shaft has an annular groove formed therein. A set screw extends through the inner ring of the outer bearing and extends into the annular groove in the shaft. A set screw extends through the inner ring of the inner bearing for frictional engagement with the shaft. A fender washer is secured to the outer end of the shaft.
