Spline Dimensions: metric involute
din 2 52 26 to din 2 82 41
Spline dimensions for three families: (1) ANSI B92.1-1970 (R1993)/1996 involute splines — flat root side fit, fillet root side fit, and major diameter fit, 30-degree pressure angle, diametral pitches 2.5/5 through 20/40; (2) ISO 14:1982/2004 straight-sided (parallel-sided) splines — light and medium series, 6/8/10 splines, metric mm; (3) DIN 5480-2:2015 metric involute splines — 30-degree pressure angle, modules m=2 and m=3, reference diameters 12–207 mm.
