Despite a higher upfront plating cost, the exclusive specification reduces total warranty and rejection expenses by 73% in this example. For high-volume, high-reputation brands, the exclusive standard is not an expense—it is an investment.
This is the metric measurement of the cut. In the notation E0.6x0.2 , the first number— 0.6 —refers to the radius (r) of the undercut's curvature measured in millimeters. This is the curved arc at the bottom of the groove. A radius of 0.6 mm is a standard industrial value used for medium-sized shafts and bores. According to the DIN 509 specifications for a Form E undercut, a radius of 0.6 mm is typically recommended for shaft diameters ranging from 3 mm up to 80 mm. This radius is the "exclusive" factor here; if a shaft is claimed to have a DIN 509 relief, the radius must be exactly 0.6 mm (within tolerance) to guarantee fitment. din 509e06x02 exclusive
