The standard is designed for torque transmission and centering between hubs and shafts, primarily in the automotive and hydraulic industries. Its core principles include:

The system uses reference diameters independent of the module, which simplifies manufacturing and assembly with standard ball or roller bearings.

It covers a module range from 0.5 to 10 mm , with tooth counts typically between 6 and 82. Structure of the DIN 5480 Series

is a German standard that defines the principles, dimensions, and inspection methods for involute splines based on reference diameters . Unlike other standards that rely on the pitch diameter, DIN 5480 uses a reference diameter that is often set to match standard bearing bores, allowing for easier integration of shafts and hubs with off-the-shelf mechanical components. Fundamental Principles of DIN 5480

DIN 5480 is strictly limited to a pressure angle of 30°.

Modern versions of the standard (revised in 2006) consolidated what used to be 16 individual documents into four primary parts: Tolerances in DIN 5480 splines | GrabCAD Tutorials

These splines are typically side-fit (flank-centered), meaning the tooth flanks handle both the torque transfer and the alignment of the mating parts.
