Din 5480 Spline Dimensions Pdf Verified

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.

Internal splines (hubs) are typically produced via broaching or shaping, while external splines (shafts) are hobbed or rolled. Ensure your dimensional limits include proper tool clearance fillets at the root.
