E Designate Nmin. value when no press–fit section is required. ex. D = 13 c N = 5 E Please designate press–fit length with N ≦ L ー F. E The N dimension also includes the head thickness and the undercut below the head, so in case of N = T + (2 or 3), there will be no press–fit part.
M Material SUJ2 H Hardness 58HRC– E Recommended mold temperature for the usage of a precision leader pin and bushing is 80°C or less because of little clearance between them.( D P.788 ) E A center hole may be left on one or both ends. E Oil groove part might not be colored by heat treatment. Despite differences in appearance, it can be used without any problem. E Please specify each dimension so that L–N–F = 10mm or more.
