Double pitch sprockets have rollers of the same diameters and widths as American Standard roller chains of 1 half the conveyor chain pitch. Engaged by every other tooth, double duty sprockets have 2 teeth per chain pitch. During each revolution only half the teeth function effectively. Sprockets with odd numbers of teeth will allow any given tooth to engage only on every other revolution, automatically increasing sprocket life. Double duty sprockets with even number of teeth may be manually advanced 1 tooth periodically to increase sprocket life.
