Din 5480 Spline Dimensions Pdf ^new^ Jun 2026

When you look at a DIN 5480 PDF chart, you will see columns of data. The most critical dimensions you need to verify are the tooth thickness and the major/minor diameters.

When searching online for a "DIN 5480 spline dimensions PDF" to use in an engineering project, keep the following best practices in mind:

: DIN 5480 offers a sophisticated system of fits and tolerances to control the clearance between mating parts. The table includes data for:

The standard covers a comprehensive range of modules and tooth combinations. For instance, modules from and tooth counts from 6 to 82 are included. The dimension tables in the official standard (PDF) for modules like 0.5, 1, 2, 3, 4, 5, 6, 8, and 10 are the primary source for all required data. din 5480 spline dimensions pdf

While the full standard requires looking up specific table values for tolerances, the basic geometry follows these rules: Reference Diameter (Note: In DIN 5480, d sub cap B

⚠️ Warning: Many “free PDFs” circulating online omit tolerances or contain OCR errors. Always cross-check with an official extract. When you look at a DIN 5480 PDF

): The primary scaling factor of the spline. Common modules range from 0.5 to 10 mm. The total count of spline teeth on the circumference. Pressure Angle ( ): Fixed at 30° for all standard DIN 5480 splines. Pitch Diameter (

The primary value used to define the spline size (e.g., in "W 120 x 3", 120 is the reference diameter). Pitch Circle Diameter ( is the module and is the number of teeth). Base Circle ( Addendum ( Dedendum ( Engineering.com Standard Structure & Documentation

) ; larger modules yield fewer, thicker teeth suited for heavy impact loads, while smaller modules yield more teeth for smooth running. Calculate or look up the . The table includes data for: The standard covers

Several companies offer a free "DIN 5480 Calculator" that outputs a custom dimension PDF for your specific spline:

DIN 5480 is the German standard for involute splines based on reference diameters. Unlike other standards that use the pitch diameter as a starting point, DIN 5480 centers the design on the outside diameter of the shaft, making it easier to match with standard bearings and seals.
