Dimensions are calculated using metric modules ( ) rather than diametral pitch.

To help you find the exact information you need from the standard, let me know what specific task you are working on. If you would like, tell me: Are you designing an or an external shaft ?

: Reliable industrial design and legal safety compliance requires a certified version from an official distributor.

: Unlike other standards (like ISO 4156), DIN 5480 is based on reference diameters that are independent of the module.

Authorized standards organizations distribute complete, legal copies of the document. Look to the , ISO store , or national distributors like ANSI and BSI . These paid PDF downloads ensure you receive the latest revisions and full data tables. 2. Version Verification

Having a physical copy of the standard is impractical for modern workflows. The is the gold standard for several reasons:

Explains how to inspect manufactured splines using GO and NO-GO gauges, as well as measuring pins. The Reference Diameter System (

Designated with uppercase letters (e.g., 9H , 7H ). H is the standard baseline, representing zero fundamental deviation.

What is the specific or nominal diameter you need to calculate?

Offers technical specifications for standard spline sizing. Tips for DIN 5480 Design

Once you have your official , here is how to apply it:

Depending on your design requirements, you can choose between three main fit categories:

Whether you are designing the or external shaft The desired tolerance class (e.g., 9g, 7H)

Official standards are protected intellectual property. DIN (the organization) invests millions in research, committee meetings, and validation. Therefore, the official PDF is a paid product.
