Din 5480 Spline - Dimensions Pdf

DIN 5480 uses a system of letters and numbers to define the "fit" between the shaft and hub.

The standard defines the dimensions and tolerances for involute splines used in mechanical engineering, particularly for serrated shaft-hub connections . Unlike older standards (e.g., DIN 5481, DIN 5482), DIN 5480 is based on a reference diameter rather than a nominal or root diameter, enabling modular design and better load distribution. din 5480 spline dimensions pdf
