is the active German technical standard that specifies the geometry, tolerances, and design requirements for straight-sided splines in the heavy series . This mechanical engineering standard dictates the parameters for secure shaft-hub connections designed to transmit exceptionally high torques under harsh operational loads. The current and active version of this document is DIN 5464:2010-03 , which directly replaced the vintage 1965 edition.

If you are working on a specific design project, let me know: What are your requirements? What torque loads will the joint experience?
0° (pressure angle), which prevents hub expansion caused by radial forces.
Before you finalize your design, keep these factors in mind: Inspection Procedures: The fundamental inspection details for DIN 5464 follow DIN ISO 14 guidelines. Load Calculation: For calculating specific load capacities, refer to DIN 5466-1 for the general mathematical basis. Material Specs: din 5464 standard pdf

Because the standard relies heavily on for the fundamental inspection and gauging methods, those procedures are not repeated in DIN 5464; they are implicitly valid and are not additionally listed.
Designed by the German Institute for Standardization ( Deutsches Institut für Normung ), this standard governs fixed and moving shaft-hub connections where extreme mechanical loads, space constraints, and high torsional stress are factors. Obtaining a legal, official copy of the DIN 5464 standard PDF is crucial for engineers, CAD designers, and industrial manufacturers looking to build reliable drivetrains without risking radial expansion under load. What is the DIN 5464 Standard? is the active German technical standard that specifies
(Number of Splines): The total count of teeth, typically ranging from 4 to 8 or more depending on the shaft size. Geometric Configuration and Centering
The is an essential resource for any engineer working with straight‑sided splines of the heavy series . The document, first published in 1965 and last updated in 2010, provides all the dimensions, tolerances, and designation rules needed for designing high‑torque shaft‑hub connections. Even though the standard is now officially withdrawn, it remains a valuable reference for legacy applications and for understanding the evolution of spline design standards.
Features parallel tooth walls. They are easier to measure with traditional calipers and micrometers but suffer from stress concentrations at the sharp root corners.
The standard accommodates multiple alignment practices for the assembled components: 0° (pressure angle), which prevents hub expansion caused
: It specifies the "fits"—how tightly the shaft and hub should slide or lock together—to ensure parts made by different manufacturers are compatible.
When checking the engineering details, you will find integrated fit clearances compiled directly from historic mechanical criteria—such as the integrated tolerance tables adopted from the withdrawn DIN 5465 framework . Procurement and Implementation
Specifies the necessary manufacturing tolerances to ensure proper fit.
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 ).
Unlike medium series (such as DIN 5463 or DIN ISO 14), the is characterized by a higher number of teeth, which allows for increased load capacity and better stress distribution across the splined connection. The standard covers both the inner (hub) and outer (shaft) profiles. Key Aspects of DIN 5464 Profile Type: Straight-sided splines (parallel-sided).
