Don't rely on guesswork for your spline geometry. Ensure your tolerances are correct and your stress calculations are based on the official data.
For more demanding applications, where higher torque density, better load distribution, and longer life are required, the family (Involute splines) is the standard of choice. Involute splines offer several key advantages:
, meaning the fit and alignment are controlled by the inside diameter ( Industry Applications

A cold draft swept through the archive. Elias looked at the last page. It wasn't a technical drawing. It was a warning written in precise, architectural script:
DIN 5462 relies on (internal centering). This means the alignment and concentricity of the mating shaft and hub are governed by the precision fit of the minor diameter (
), measured at the root of the external shaft or the tip of the internal hub. : The major diameter ( Don't rely on guesswork for your spline geometry

DIN 5462 defines the for lower torque applications, while DIN 5464 defines the heavy series for higher torque applications. Both use straight-sided spline geometry but differ in tooth dimensions and load capacity. Involute splines offer several key advantages: , meaning

Standard for hydraulic pumps where the pump is bolted tight to a PTO face, preventing axial movement. Engineering Advantages of Straight-Sided Splines
Purchase your official copy via Beuth Verlag or request an interlibrary loan of the 1977 edition. Your machinery’s reliability depends on it.
The DIN 5462 standard, established by the Deutsches Institut für Normung (German Institute for Standardization), defines the dimensions and tolerances for straight-sided (parallel) splines. It specifically targets heavy-duty linkages where a hydraulic pump or motor mounts directly to a vehicle's transmission or PTO gearbox. Key Characteristics of DIN 5462
