The standard specifies the dimensions, tolerances, and design requirements for metric parallel spline shaft connections . Originally published in 1955, it has largely been superseded by the international standard ISO 14 , though it remains a common reference in industrial catalogs and technical drawings for "medium series" straight-sided splines. Overview of DIN 5463

Because DIN 5463 relies on internal centering, the tolerances on the minor diameter ( ) are highly precise to prevent runout and vibration. din 5463 pdf

Applications and Engineering Considerations The following table summarizes common sizes found in

Because straight-sided splines distribute rotational force evenly across multiple parallel faces, they are vastly superior to single-keyway systems. DIN 5463 profiles are commonly found in:

Machined ends may require re-straightening and lapping, particularly if multiple bushes are used on a single shaft. Conclusion

Unlike involute splines, the sides of the splines in DIN 5463 are parallel, facilitating easier manufacturing for certain applications.
