The benefit of using a side guide roller does not often go unappreciated. To keep the belt centered and to train new belts, side guide rollers are used. The location of Side Guide Rollers on the carrying side should be quite distant from the head pulley and then at considerable intervals. Side Guide Rollers in the return run of the belt should be located 10-12 feet ahead of the tail pulley so as to center the belt as it enters the tail pulley. Though the measurement does not necessarily be the same for every usage and can be altered at the time of inception.
