specifically covers Serrations (involute serrations) – 30° pressure angle, module 0.5 to 2 – Dimensions . In practical terms:

DIN 5463 was part of a comprehensive family of German standards for splined connections. These standards were meticulously designed to ensure compatibility and reliability across different applications.

However, there is a major caveat:

In this system, the variables represent:

The DIN 5463 standard defines spline profiles based on three primary dimensions: the number of splines ( ), the minor diameter ( ), and the major diameter ( Profile Element Description Typically ranges from 6 to 20 for standard sizes. Inside Diameter ( ) The core diameter of the shaft (minor diameter). Outside Diameter ( ) din 5463 pdf

If you have determined that you truly need the original DIN 5463 (not ISO 14), follow this step-by-step plan:

Unlike involute splines (which feature curved, gear-like teeth), straight-sided splines have straight, parallel flanks. DIN 5463 specifically details the ( leichte Reihe ) of these splines, which are typically used for applications requiring a balance of robust torque transmission and ease of manufacturing. Key Characteristics of DIN 5463: Profile Type: Straight-sided / Parallel-sided.

): The thickness of the straight-sided tooth on the shaft, corresponding to the slot width in the hub. Standard Dimension Table (DIN 5463 Quick Reference)

Typically machined to g6 or h6 on the minor diameter to ensure a slide fit or close running fit.

These dimensions were critical for ensuring that a splined shaft and its matching hub would fit together precisely. The table below shows a selection of nominal dimensions from the standard, including key widths and other key geometric features:

Companies like Misumi, Maska, or local gear manufacturers often provide free DIN 5463 dimensional tables in PDF format or downloadable 3D CAD steps.

Provide which country or institution you prefer (or say “institutional access”) and I’ll outline the most direct options and likely costs. If you want, I can also summarize key clauses once you provide the PDF or its clause numbers. DIN 5463 specifically details the ( leichte Reihe

DIN 5463 has been officially withdrawn and replaced by the international standard ISO 14 .

DIN 5463 specifies dimensions and tolerances for hexagon spline sockets (also called hexagon broached splines or hexagon drive sockets ). These are internal drives used in screws, bolts, or shaft-hub connections—not to be confused with external involute splines.
