DIN 5463 is a German standard that defines the requirements for involute splines and their corresponding mating parts. The standard is published by the German Institute for Standardization (DIN) and is widely used in various industries, including mechanical engineering, automotive, and aerospace. In this article, we will provide an overview of the DIN 5463 standard, its contents, and its significance. We will also discuss how to obtain a PDF copy of the standard.

Splined Sleeves acc. to DIN 5463 / ISO 14 (C45) - TraceParts
Standard profiles are designated by their primary dimensions (e.g.,
Despite being replaced by ISO 14 (Straight-sided splines for cylindrical shafts with internal centering), the designation "DIN 5463" remains incredibly popular in European workshops, legacy blueprints, and aftermarket parts catalogs. Manufacturers frequently cross-reference DIN 5463 with ISO 14 because their dimensions and fitment characteristics are nearly identical. How to Find and Download a DIN 5463 PDF din 5463 pdf
: Excellent guide on the transition from DIN 5463 to ISO 14, including material strengths like Steel (C45) or Stainless Steel.
That said, if you are designing new tooling or a new broaching machine, you (or the international equivalent ISO 10767 for splines, though hexagons remain national). Do not design new components to DIN 5463 unless you are explicitly repairing an existing system.
If you are currently designing a drivetrain component, let me know: What is your required ?
: Features straight, parallel flanks. The flank of each key must remain parallel to the inside diameter. Spline Count : Typically consists of for smaller diameters (up to size for larger diameters ( Core Dimensions : Defined by three primary parameters: : Inside (minor) diameter. : Outside (major) diameter. : Width of the spline/key. : Generally uses internal centering (on the minor diameter ), though flank centering is also a design option.
