The shaft was manufactured and, as recommended, the dimensions were tightly controlled, particularly the key widths and diameters, using tolerances to ensure a precise, smooth fit with the coupling.
Complete Guide to DIN 5463: Specifications, Dimensions, and PDF Resources What is DIN 5463?
Straight-sided splines can be easily milled, hobbed, or shaped compared to complex involute geometries.
Internal centering is standard for spline bores (Profile A), though not always possible for all shaft profiles during the hobbing process. Tolerances: Inner diameter ( din 5463 pdf
Don't risk a recall. Obtain the standard from an authorized national standards body:
Features straight, parallel flanks (unlike involute splines which have curved teeth).
Tooling (such as broaches and hobs) for standard DIN 5463 dimensions is readily available off the shelf. Limitations The shaft was manufactured and, as recommended, the

Excellent for applications where components must slide axially while under minimal load.
