❌ Stating both dref and z incorrectly – e.g., W 50 x 2.5 x 22 – 50/2.5 = 20 teeth, not 22. The tooth count is mathematically fixed.

Indicates the component type. W stands for Welle (Shaft), while N stands for Nabe (Hub/Internal Spline). 35: The nominal reference diameter ( 2: The module ( 16: The number of teeth (

A common point of confusion is how DIN 5480 relates to other major international spline standards. Here's a direct comparison: Din 5480 Pdf

To inspect the manufactured part, refer to the tables in the PDF to find the exact dimensions over pins ( Mkcap M sub k for external) or between pins ( Mdcap M sub d

I have reviewed hundreds of spline callouts. Here are the most frequent errors when using DIN 5480: ❌ Stating both dref and z incorrectly – e

❌ Omitting tolerance class. Without 8f or 9H , the manufacturer cannot determine the effective tooth thickness.

Always designated with uppercase letters (typically H ). W stands for Welle (Shaft), while N stands

To ensure you are working with the most up-to-date, legally compliant, and accurate data for manufacturing or design, you should access the documents directly through official distribution channels:

is a prominent German engineering standard that specifies the geometry and dimensions for involute splined joints . Unlike some other spline standards, it is based on reference diameters that are independent of the module, allowing for easier integration with standardized ball or roller bearings. Key Characteristics of DIN 5480 Pressure Angle : Standardized at 30° .

Unlike simple parallel keys or serrations, involute splines offer superior centering, higher torque transmission, and longer fatigue life. However, finding a clear, consolidated explanation of the actual PDF content is difficult. Below, I break down exactly what the DIN 5480 standard contains, how to read its naming convention, and how to apply it.
