Din 5480 Spline Dimensions Pdf Verified !exclusive! Jun 2026

Ensure the PDF accounts for the machining method (broaching vs. hobbing) as this affects the root clearance.

Below is a verified dimensional reference table for common industrial DIN 5480 sizes. These values represent the nominal geometry before tolerances and fit classes are applied.

Ensure it uses standard metric modules (e.g., 1.25, 2, 3, 5, 8).

The official standards are available from the following sources:

If you need to calculate dimensions for a specific profile, tell me the , module , or number of teeth , and I will generate the exact geometric data you need. Share public link

Ensure the relationship between module and tooth count perfectly aligns with the stated reference diameter. Ensure the PDF accounts for the machining method

For production environments, utilize full-form spline plug and ring gauges. If a "Go" gauge inserts freely and the "No-Go" gauge binds, the splined geometry functions correctly within standard specifications.

Quality inspections, deviations, and effective fit concepts. The standard utilizes a 30° pressure angle (

: Loose or clearance fits, ideal for components that must slide axially under zero load. h : Standard sliding fit with minimal backlash.

: Focus on specific inspection methods and measurement tolerances. Decoding the DIN 5480 Designation ( df2d sub f 2 end-sub W 25 x 1

Contact occurs on either the outside diameter (major) or inside diameter (minor).

The defining characteristic of a DIN 5480 spline is a . Pressure angles of 37.5° and 45° are covered by the ISO 4156 standard, and splines from these two standards are not interchangeable.

The modern version of the standard is now organized into a clear, four-part series:
