The defines the dimensions and tolerances for involute splines based on reference diameters, ensuring high torque transmission and precise centering. Unlike other standards, it is designed so that the reference diameter often matches standard ball or roller bearing bores to allow for easier assembly and slip-fitting of components. Understanding the DIN 5480 Designation
