Engineers, machinists, and quality inspectors frequently search for a verified to eliminate calculation errors during the design-to-manufacturing handoff. This article breaks down the core geometry, reference diameters, module selections, and fit classes defined by DIN 5480. 1. Understanding DIN 5480 Standards Structure

: Denotes an external shaft spline ( N for Nabe/Hub). 120 : Reference diameter in millimetres. 3 : Module (tooth size). 38 : Total number of teeth. 8f : Tolerance class (8) and deviation series (f). Verified PDF Resources 38 : Total number of teeth
DIN 5480 covers a range of modules (e.g., 0.5 — 10+), with standardized tooth counts and corresponding diameters to suit different torque levels and shaft sizes. Selection depends on required torque capacity, material strength, and manufacturing method. Selection depends on required torque capacity
Where dm = ball diameter (0.6m to 1.1m typically).
The PDF usually contains an introduction explaining the advantage of the DIN 5480 geometry over straight-sided splines:
