DIN 5480 Spline Dimensions: A Comprehensive Guide

6. Tooth Thickness & Space Width (at reference diameter)

• For basic rack tooth thickness = π*m/2
• Actual values vary by fit class (e.g., h, f, e, d for external; H, G, F, E for internal).

6. Recommendations for Engineers

1. Do not trust scanned PDFs of DIN 5480 unless accompanied by a digital hash from DIN Media GmbH.
2. Verify three critical values manually using the formulas in Section 3 before releasing to production.
3. Prefer native digital PDFs (not scanned) with searchable tables – these typically maintain numeric precision.
4. Cross-reference with ISO 4156 for internal spline major diameter formulas, as DIN 5480 Appendix C references ISO calculations.
5. Use a spline calculation software (e.g., MITCalc, KISSsoft) as a secondary verifier against the PDF.

A typical callout (e.g., DIN 5480 – W 120 x 3 x 38 x 8f) is decoded as follows: Din 5480-2 | PDF | Engineering Tolerance | Gear - Scribd din 5480 spline dimensions pdf verified
