The configuration profiles use a standardized naming convention based on the tooth count ( ), minor diameter, and major diameter:
The DIN 5464 standard establishes the dimensional profiles, tooth counts, boundary geometries, and tolerance zones for straight-sided (parallel-flanked) splines categorized under the "Heavy Series" ( Schwere Reihe ).
The standard is favored in specific heavy-duty sectors because of its inherent design advantages: din 5464 standard pdf

Compared to light (DIN 5462) or medium (DIN 5463) series, DIN 5464 implements a greater number of teeth alongside thicker tooth proportions. This modification yields a substantially elevated total load capacity. Always verify you have the latest revision and

While many third-party engineering blogs offer summarized dimension charts, the official, legally binding must be purchased through authorized distributors such as Beuth Verlag or the ISO Store. Utilizing unauthorized or outdated PDFs from unverified sources can result in using obsolete tolerances, causing structural failures or mating components that do not fit. English | €46.00 (German)

DIN 5464 defines dimensions, while is for engineering calculations. To design a durable joint, engineers must follow the dimensional rules of DIN 5464 and then use the formulas in DIN 5466-1 to verify it against fatigue and yielding under real operating loads.
