The DIN 5463 standard remains a cornerstone of mechanical power transmission design despite its technical replacement by ISO 14. Its reliance on internal centering makes it an ideal profile for high-concentricity, high-torque applications. When searching for a , ensure you are consulting verified engineering tables or purchasing the official historical document to maintain absolute precision in your manufacturing pipeline.
Many precision component manufacturers provide free technical data sheets. Look for product catalogs from spline shaft manufacturers. These documents contain identical dimension tables, tolerances, and CAD profile data in PDF format without requiring a paid subscription. Share public link
The standard is a widely recognized German industrial specification for metric parallel spline shaft connections with straight flanks, specifically the "medium series". Although formally replaced by DIN ISO 14 , it remains a critical reference for engineers and maintenance professionals working with legacy machinery and standardized power transmission components. Key Specifications and Applications
Straight, parallel flanks where the flank of each key is parallel to the inside diameter.

Withdrawal means the standard is no longer maintained and cannot be purchased as a current standard from official sources. As noted on the official shop of the German Institute for Standardisation (DIN Media), it is categorized as "superseded" and is not available for purchase in many regions. The German Wikipedia list of DIN standards also notes that a "withdrawn" standard may have no replacement. However, it is essential to clarify that in the case of DIN 5463, .
All nominal dimensions are in millimeters (mm).

The standard covers spline shaft profiles (designated A or B) and corresponding splined bores. Common profile sizes include:
