Eccentric Shaft The throw-to-throw accuracy of Minster's one-piece forged eccentric shaft is within ±.0005" (,0127 mm) to provide superior dynamic parallelism that results in increased die life in close tolerance dies. Eccentric shafts provide more accuracy and higher rigidity than eccentric gears or crankshafts, and they have approximately 33 percent more load bearing area and less deflection than a standard crankshaft. This design significantly increases the press's ability to handle snap-thru forces as compared to a crankshaft or eccentric gear design.
