Unlike other spline standards that focus on the pitch diameter, DIN 5480 is based on the reference diameter (
If you need the standard for professional engineering work, you must obtain it legitimately. Here are the official vendors: Din 5480 Pdf
However, navigating this standard can be tricky. Because the standard has evolved through various versions (DIN 5480-1, DIN 5480-2, etc.) and was eventually superseded by ISO standards, finding the correct document is half the battle. Unlike other spline standards that focus on the
The standard officially replaced older spline standards in the 1980s and has since been harmonized with international standards like ISO 4156 (though specific differences remain). The standard officially replaced older spline standards in
📄 The PDF contains tables for , minor diameters , and form diameter limits for each tolerance class. You cannot guess these – they are calculated per module and tooth count.
