), denotes a shaft (Welle), and N denotes a hub/internal spline (Nabe). 4. Tolerance Classes and Fit Systems

Proper selection of tolerance classes (e.g., 7e, 8f, 9h) is necessary to achieve the desired fit (sliding, transition, or interference). : Covers basic parameters and the reference diameter system

7H/7e or 8H/8f (Good for precision and high-load torque). Clearance Fit: 9H/9e (Good for easy assembly).

A verified PDF will only contain modules from the R10 or R20 series. If your PDF lists m = 2.3 mm, it is fraudulent. Standard modules: 0.5, 0.6, 0.8, 1, 1.25, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10. If you share with third parties, their policies apply

The DIN 5480 standard was first published in 1966 by the German Institute for Standardization (DIN). The standard was developed to provide a uniform set of dimensions and tolerances for splines used in various industries, including automotive, aerospace, and machinery. Over the years, the standard has undergone several revisions, with the most recent update being published in 2019.

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.

Let’s verify what these numbers mean using the standard:

: Nominal dimensions and space widths for specific modules.
